How do you do this help me and Explain how I will give you Brainless

Simplify 15 by dividing it by 3, and then shade 2/3rds of the simplified sections. This should come out to 3 sections of five, so shade in 10 out of the 15 sections

The easiest way to understand this question is to give both fractions the same denominator. Only one fraction? Nope, it says the pie is split into 15 pieces, making 15 and 3 the denominators. As for the numerators, the question has given you only one, and is asking for the numerators above 15 (aka, the number of pieces you need colour).

With this in mind, all you need to do is set up a ratio:

2/3 = ?/15

Well how do you get 3 x ? = 15? Rearrange the equation to 15/3 = 5

So now we know to times the demonimator by 5 to get 15, and to keep the ratio the same we must do the exact same thing to the numerator.

2 x 5 = 10

That leaves us with 2/3 = 10/15

Therefore, you should colour 10 pieces.
