Question

Taira used 3/4 of her flour to make 2/5 of a batch of bannock. How much of her flour would she need to make a whole batch?

Answer 1

15/8 or 1.875

Explanation:

Let x represent a whole batch of bannock. Taira used 3/4 of her flour to make 2/5 of a whole batch so we can write the equation like this.

3/4=2/5x

Isolate x by multiplying the left side by the reciprocal of 2/5.

15/8=x
