Answer 2

What does it mean to be proportional?

For two numbers to be proportional, they need to be directly increasing or decreasing in a constant ratio.

To simplify these ratios, we can use division.

• 7: 14 = 1: 2

1. (7 ÷ 7 = 1)
2. (14 ÷ 7 = 2)

So, 7: 14 simplified is 1: 2.

• 4: 8 = 1:2

1. (4 ÷ 4 = 1)
2. (8 ÷ 4 = 2)

So, 4: 8 simplified is 1: 2.

If these ratios are both simplified to equal 1 :2, they are proportional.
