Question

Goran needs to read 3 novels each month.

Let N be the number of novels Goran needs to read in M months.
Write an equation relating N to M. Then use this equation to find the number of novels Goran needs to read in 15 months.

Answer 1

45

Explanation:

If Goran reads 3 novels every months then you can set up the equation with:

n = m

n = 3

In 15 months, you just multiply the equation by 15, because what you do to one side of the equation, you have to do to the other.

15n = 15m

n is equal to 3, so Goran needs to read 15 x 3 = 45 novels in 15 months.
