Question

which expressions represent the same amount as 271? choose 2 answers: a 27 tens +1 one b 1 hundred + 12 tens+ 1 one c 22 tens + 7 tens +1 one

Explanation:

Step1: Analyze Option A

27 tens is \(27\times10 = 270\), and 1 one is \(1\times1 = 1\). So \(27\times10+1\times1 = 270 + 1=271\).

Step2: Analyze Option B

1 hundred is \(1\times100 = 100\), 12 tens is \(12\times10 = 120\), and 1 one is \(1\times1 = 1\). So \(100+120 + 1=221 eq271\).

Step3: Analyze Option C

22 tens is \(22\times10 = 220\), 7 tens is \(7\times10 = 70\), and 1 one is \(1\times1 = 1\). So \(220+70 + 1=291 eq271\)? Wait, no, wait: 22 tens +7 tens is (22 + 7) tens = 29 tens? Wait, no, original option C: 22 tens +7 tens +1 one. Wait, 22 tens is 220, 7 tens is 70, so 220 + 70 = 290, plus 1 is 291. Wait, that's wrong. Wait, maybe I made a mistake. Wait, the original number is 271. Let's re - check Option A: 27 tens is 27*10 = 270, plus 1 one is 271. Correct. Option B: 1 hundred (100) +12 tens (120) +1 one (1) = 100 + 120+1 = 221. Incorrect. Option C: 22 tens (220) +7 tens (70) +1 one (1) = 220 + 70+1 = 291. Incorrect. Wait, maybe there is a typo? Wait, maybe Option C is 20 tens +7 tens +1 one? No, the given is 22 tens +7 tens +1 one. Wait, maybe I misread the options. Wait, the user's options: A:27 tens +1 one; B:1 hundred +12 tens +1 one; C:22 tens +7 tens +1 one. Wait, maybe the correct options are A and another one. Wait, maybe I made a mistake in Option B. Wait, 1 hundred is 100, 12 tens is 120, 1 one is 1. 100+120 +1 = 221. No. Wait, maybe the intended Option B was 1 hundred +17 tens +1 one? No. Wait, maybe the original problem has a different option. Wait, maybe I made a mistake in Option C. Wait, 27 tens is 270, which is 20 tens +7 tens. So 20 tens +7 tens +1 one is 200 + 70+1 = 271. But Option C is 22 tens +7 tens +1 one. 22 tens is 220, 7 tens is 70, so 220 + 70 = 290, plus 1 is 291. So that's wrong. Wait, maybe the options are different. Wait, the user's screenshot: Option A:27 tens +1 one; Option B:1 hundred +12 tens +1 one; Option C:22 tens +7 tens +1 one. Wait, maybe the correct answers are A and another option. Wait, maybe I made a mistake in Option B. Wait, 1 hundred is 100, 12 tens is 120, 1 one is 1. 100 + 120+1 = 221. No. Wait, maybe the problem has a typo. But according to the calculation, Option A is correct (27*10 +1 = 271). Let's check again. 27 tens is 27*10 = 270, plus 1 one is 271. Correct. Now, maybe there is another option. Wait, maybe the user made a mistake in the options, but according to the given options, only Option A is correct? But the problem says to choose 2 answers. Wait, maybe I misread Option C. Wait, 22 tens +7 tens is 29 tens? No, 22 + 7 = 29, 29 tens is 290, plus 1 is 291. No. Wait, maybe Option B is 1 hundred +17 tens +1 one? Then 100+170 +1 = 271. But the given is 12 tens. So maybe there is a mistake in the problem. But according to the given options, only Option A is correct. But the problem says to choose 2 answers. Maybe I made a mistake. Wait, let's re - calculate:

Option A: 27 tens = 27*10 = 270, 1 one = 1, 270+1 = 271. Correct.

Option B: 1 hundred = 100, 12 tens = 12*10 = 120, 1 one = 1. 100 + 120+1 = 221. Incorrect.

Option C: 22 tens = 22*10 = 220, 7 tens = 7*10 = 70, 1 one = 1. 220+70 +1 = 291. Incorrect.

Wait, maybe the options are different. Maybe Option C is 20 tens +7 tens +1 one? Then 20*10+7*10 +1 = 200 + 70+1 = 271. But the given is 22 tens. So perhaps there is a typo. But based on the given options, only Option A is correct. But the problem says to choose 2 answers. Maybe I misread the options. Wait, the user's options:

A:27 tens +1 one

B:1 hundred +12 tens +1 one

C:22 tens +7 tens +1 one

Wait, maybe the correct options are A and another one. Wait, maybe the original problem has a different set of options. Alternatively, maybe I made a mistake in Option B. Wait, 1 hundred is 100, 12 tens is 120, 1 one is 1. 100+120 +1 = 221. No. So perhaps the problem has an error. But according to the given options, the correct answer for one of them is A. But the problem says to choose 2. Maybe there is a mistake in my analysis.

Wait, wait, 271 can be written as 27 tens +1 one (27*10 +1 = 271) and also as (22 + 5) tens +1 one? No, Option C is 22 tens +7 tens +1 one. 22 + 7 = 29 tens, which is 290, plus 1 is 291. So that's wrong. So maybe the correct answers are A and another option that is not shown? But based on the given options, only A is correct. But the problem says to choose 2. Maybe there is a mistake in the problem or in my analysis.

Wait, maybe Option B is 1 hundred +17 tens +1 one? Then 100+170 +1 = 271. But the given is 12 tens. So perhaps it's a typo. Alternatively, maybe the user made a mistake in the options. But based on the given options, the correct answer for one of them is A. But since the problem says to choose 2, maybe I made a mistake.

Wait, let's re - check:

271 in place value: 2 hundreds, 7 tens, 1 one. Which is 27 tens (2*100 = 200 = 20 tens, 7 tens, so 20 + 7 = 27 tens) and 1 one. So 27 tens +1 one = 271. Correct.

Another way: 22 tens +5 tens +1 one? But Option C is 22 tens +7 tens +1 one. 22 + 7 = 29 tens. So that's 290 +1 = 291. So no.

So perhaps the correct answers are A and another option that is not present here. But based on the given options, only A is correct. But the problem says to choose 2. So maybe there is a mistake.

But according to the initial analysis, Option A is correct. If we assume that there is a typo in Option C (22 tens should be 20 tens), then Option C would be correct. But with the given options, only A is correct. But the problem says to choose 2. So perhaps the intended options are A and C (if 22 tens is a typo for 20 tens). But with the given options, the correct answer for one of them is A.

Answer:

A. 27 tens +1 one
