Answer:

<u>1. The number is 71.3</u>

<u>2. The number is 127.1</u>

<u>3. The number is 230</u>

<u>4. The number is 34</u>

Step-by-step explanation:

Let's find out the numbers, x, for each case:

1. 5% of it is 5% of it is 23% of 15.5

5% = 0.05

23% of 15.5 = 0.23 * 15.5 = 3.565

Then, we have:

0.05x = 3.565

x = 3.565/0.05

x = 71.3

<u>The number is 71.3</u>

2. 4% of it is 31% of 16.4

4% = 0.04

31% of 16.4 = 0.31 * 16.4 = 5.084

Then, we have:

0.04x = 5.084

x = 5.084/0.04

x = 127.1

<u>The number is 127.1</u>

3. 4.5% of it is 23% of 45

4.5% = 0.045

23% of 45 = 0.23 * 45 = 10.35

Then, we have:

0.045x = 10.35

x = 10.35/0.045

x = 230

<u>The number is 230</u>

4. 5.5% of it is 17% of 11

5.5% = 0.055

17% of 11 = 0.17 * 11 = 1.87

Then, we have:

0.055x = 1.87

x = 1.87/0.055

x = 34

<u>The number is 34</u>
