Answer:
15 muffins
Step-by-step explanation:
We can use proportion to solve this.
Let x be the number of muffins that can be made with 5 cups of flour
4 cups = 12 muffins
5 cups = x
cross-multiply
4×x = 12 × 5
4x = 60
Divide both-side of the equation by 4
=
(On the left-hand side of the equation, 4 on the numerator will cancel-out 4 on the denominator, while on the right-hand side of the equation 60 will be divided by 4)
x = 15 muffins
15 muffins can be made with 5 cups of flour.
