5/12 DOES equal 5:12 but there is another way to do it ..

you can also put 5:7 because 5+7=12 and 12 is the denominator for this question .. personally i like to put 5:7 because its not the same as the fraction

Mr.H, you got this question wrong because you figured out the denominator incorrectly.
5/12 is not equivalent to 5:12.

To get the correct answer, this is what you have to:

First, figure out the denominator (bottom number). To do this you have to add both numbers in the ratio. In this case you add 5+12=17.

The first number in the ratio will be the numerator (top number). In this case the numerator is 5.

For example:
You have a pizza with 12 slices and you ate 5 slices.
= 5:12 = 5/17
The denominator (12) represents the whole pizza and the numerator (5) represents the amount of slices you ate.

**Remember ratio is part to part and fraction is part to whole.

At the bottom of my comment, I made a mistake. I put 12 for my denominator instead of 17.

5/12= 5:12

On his ratio, his denominator was wrong.
