Question

If I have a ratio 2:6, then what is x/18?
f I have a ratio 5:7, then what is (x+3):7?

Answer 1

1. x=6

2. x=2

Explanation:

2:6

x:18

From 6 to 18, 6 was multiplied by 3. To keep the equality, we must multiply the other side by three as well. Therefore, x is equal to 2*3 which equals 6.

x=6.

5:7

(x+3):7

For this one, the second value did not change, so we know that x+3 has to equal 5. Therefore, x=2.

x=2
