Question

Drag the numbers to create three ratios that are equivalent to 4:12.Numbers can only be used once.Pls help

Answer 1

ANWERS

20 : 60

12 : 36

2 : 6

Step-by-step explanation

To create equivalent ratios we have to multiply or divide the numerator (the number on the left) and the denominator (the number on the right) by the same number.

For the first equivalent ratio we have to find the denominator given that the numerator is 20. We know that 20 is 4 times 5, this means that the numerator has been multiplied by 5 and, therefore, we have to multiply the denominator by 5 as well:

`12*5=60`

For the second equivalent ratio we have to find the numerator given that the denominator is 36. 36 is 3 times 12. This means that we have to multiply the numerator by 3:

`4*3=12`

For the third equivalent ratio we have the denominator that's 6. In this case, instead of multiplying we have to divide, because 6 is 12 divided by 2. Therefore, we have to divide the numerator by 2:

`4\colon2=2`
