I also got the same answer which is 2, because as you see in example number 1, if you used cross-multiplication, the answer were equal which is 20=20 but in the problem, it's 15=15.

If you use cross-multiplication: 2 x 7.5 = 15 6 x 2.5 = 15

15 = 15

If you divide the numerator to the denominator: 2 / 6 = 0.33333333..... 2.5 / 7.5 = 0.33333333.....

0.333... = 0.333...

If you divide numerator to numerator and denominator to denominator:

2 / 2.5 = 0.8 6 / 7.5 = 0.8

0.8 = 0.8

The fractions 2/6 and 2.5/7.5 is an equivalent fraction.

I think the answer is 2 because when you divide it by 6 it equals to = 0.333333333

and when you divide 2.5 to 7.5 the answer is also 0.333333333

it's the same.

yeah (:

My answer is the same as Trish's.

I think the answer is 2.

Here is how I got the answer:

x/6 = 2.5/7.5

7.5/6= 1.25

2.5/1.25= 2

2/6 = 2.5/7.5

To make sure my answer was right I used multiplication:

2x1.25= 2.5

6x1.25= 7.5

2/6 = 2.5/7.5
