Answer 2

Hi there,

Answer:

x=28

(Ratio: 4:9 = 28 :63)

How to write the working-out:

63 ÷ 9 = 7

4 × 7 = 28

x = 28

Step-by-step explanation:

First, you need to figure out what number was multiplied to the 1st ratio to get the 2nd ratio.

To figure out a the multiple, you can do this:

Answer ÷ Number = Multiple

63 ÷ 9 = 7

So we figure out that the 1st ratio was multiplied by 7 to get the 2nd ratio.

If 7 × 9 = 63, 4 × 7 = x

We multiply the 4 with the 7 to figure out what x is.

4 × 7 = 28

So the answer is 28.

I hope this helps. :)
