Question

which expressions represent the same amount as 342? choose 2 answers: a 3 hundreds + 42 tens b 3 hundreds + 4 ones+ 2 ones c 3 hundreds + 42 ones

Explanation:

Step1: Analyze Option A

3 hundreds is $3\times100 = 300$, 42 tens is $42\times10 = 420$. Then $300 + 420 = 720
eq342$. So Option A is incorrect.

Step2: Analyze Option B

3 hundreds is $3\times100 = 300$, 4 ones is $4\times1 = 4$, 2 ones is $2\times1 = 2$. Then $300+4 + 2=306
eq342$. Wait, maybe there is a typo? Wait, maybe it's 4 tens? Wait, no, the option says 4 ones + 2 ones. Wait, maybe I misread. Wait, the original number is 342, which is 3 hundreds, 4 tens, 2 ones. Wait, let's re - check Option C: 3 hundreds is 300, 42 ones is 42. So $300 + 42=342$. So Option C is correct. Wait, maybe I made a mistake in Option B. Wait, maybe the option B is 3 hundreds + 4 tens+2 ones? But the option says 4 ones + 2 ones. Wait, maybe the user's option B has a typo, but according to the given options, let's re - evaluate. Wait, the correct breakdown of 342 is 3 hundreds, 4 tens, 2 ones. Let's check Option C: 3 hundreds ($3\times100 = 300$) + 42 ones ($42\times1 = 42$), $300 + 42=342$. Now, let's check another possible correct option. Wait, maybe there is another option (probably a missing option in the user's provided image, but among the given options, Option C is correct. Wait, the user's image shows Option C as 3 hundreds + 42 ones, which is correct. Also, maybe there is another option, but based on the given options, let's re - check. Wait, maybe the first option A was mis - calculated. Wait, no, 42 tens is 420. Wait, maybe the user's options are a bit different. Wait, let's re - express 342: 342 = 3×100+4×10 + 2×1=300 + 40+2. Now, 3 hundreds + 42 ones: 3×100+42×1 = 300 + 42=342 (Option C is correct). Also, if there is an option like 3 hundreds+4 tens + 2 ones, but in the given options, let's check again. Wait, maybe the original problem has a different set of options. Wait, the user's provided options: A: 3 hundreds + 42 tens, B: 3 hundreds + 4 ones+2 ones, C: 3 hundreds + 42 ones. Wait, maybe there is a missing option, but among the given, Option C is correct. Wait, maybe I made a mistake in Option B. Wait, 4 ones + 2 ones is 6 ones, 3 hundreds is 300, 300+6 = 306. So Option B is wrong. Wait, but the problem says to choose 2 answers. Maybe there is a typo in the options. Wait, maybe Option A was supposed to be 3 hundreds+4 tens + 2 ones? No, the option says 42 tens. Alternatively, maybe the user made a mistake in the options. But based on the given options, Option C is correct. Wait, maybe there is another correct option. Wait, let's re - calculate Option C: 3 hundreds is 300, 42 ones is 42. 300+42 = 342. So Option C is correct. If we assume that there is a typo in Option B and it's 3 hundreds + 4 tens+2 ones, but as per the given text, Option B is 3 hundreds + 4 ones+2 ones. So among the given options, Option C is correct. But the problem says to choose 2 answers. Maybe there is a missing option or a typo. Wait, maybe I misread Option A: 3 hundreds + 42 tens? No, 42 tens is 420. 300 + 420=720. Option C: 300+42 = 342. Maybe there is another option, like 34 tens+2 ones? No, the options given are A, B, C. Wait, maybe the original problem has more options, but in the given ones, let's confirm:

Option C: 3 hundreds ($3\times100 = 300$) + 42 ones ($42\times1 = 42$). $300+42 = 342$. So Option C is correct.

Wait, maybe the user made a mistake in the options, but if we consider that maybe Option B was supposed to be 3 hundreds + 4 tens+2 ones (which is 300 + 40+2 = 342), but the option says 4 ones + 2 ones. So perhaps there is a typo. But based on the given options, the correct one is C. But the problem says to choose 2 answers. Maybe there is a missing option or a typo. Alternatively, maybe I made a mistake. Wait, let's re - check the number 342. 342 can be written as 3 hundreds + 42 ones (since 42 ones is 42, 300+42 = 342) and also as 3 hundreds+4 tens + 2 ones (300 + 40+2 = 342). If Option B was supposed to be 3 hundreds + 4 tens+2 ones, but it's written as 4 ones + 2 ones, that's a typo. But among the given options, Option C is correct. If we assume that there is a mistake and Option B is 3 hundreds + 4 tens+2 ones, then both B and C would be correct. But as per the given text, Option B is 3 hundreds + 4 ones+2 ones. So maybe the correct answers are C and another one (maybe a typo in the options). But based on the given options, the correct answer for one of them is C. Wait, maybe the original problem has a different set of options. Given the current options, let's proceed.

Answer:

C. 3 hundreds + 42 ones

(Note: There might be a typo in the options. If we assume that Option B was supposed to be 3 hundreds + 4 tens+2 ones, then B and C would be correct. But based on the given text of the options, only C is correct. However, since the problem says to choose 2 answers, there might be a mistake in the option presentation.)
