for each question below, you will be given 4 numbers. you will need to find which pair of these numbers can be divide to give a number within a desired range.
there is only one pair of numbers that works, and as soon as you find it, you can enter that answer.
question 1: choose the two of the following that when divided have a result close to 0.8 (the result will be the only result between 0.68 and 0.92).
0.17
0.2
0.4
3.3
question 2: choose the two of the following that when divided have a result close to 0.4 (the result will be the only result between 0.34 and 0.46).
170
350
900
4000
question 3: choose the two of the following that when divided have a result close to 200 (the result will be the only result between 170 and 230).
0.4
2
7
1500

Explanation:

Question 1

Step1: Test all valid pairs

$\frac{0.17}{0.2}=0.85$, $\frac{0.17}{0.4}=0.425$, $\frac{0.17}{3.3}\approx0.0515$, $\frac{0.2}{0.4}=0.5$, $\frac{0.2}{3.3}\approx0.0606$, $\frac{0.4}{3.3}\approx0.1212$

Step2: Check range fit

0.85 is between 0.68 and 0.92.

Question 2

Step1: Test all valid pairs

$\frac{170}{350}\approx0.4857$, $\frac{170}{900}\approx0.1889$, $\frac{170}{4000}=0.0425$, $\frac{350}{900}\approx0.3889$, $\frac{350}{4000}=0.0875$, $\frac{900}{4000}=0.225$

Step2: Check range fit

0.3889 is between 0.34 and 0.46.

Question 3

Step1: Test all valid pairs

$\frac{1500}{0.4}=3750$, $\frac{1500}{2}=750$, $\frac{1500}{7}\approx214.29$, $\frac{2}{0.4}=5$, $\frac{7}{0.4}=17.5$, $\frac{7}{2}=3.5$

Step2: Check range fit

214.29 is between 170 and 230.

Answer:

1. 0.17 and 0.2
2. 350 and 900
3. 1500 and 7
