Question

a bread recipe calls for 4 eggs for every 1 and a half pounds of flour you use. If you had 12 pounds of flour, how many eggs would you need to make all the bread that you could?

Answer 1

Firstly, we need to find the number which, when multiplied with 1 1/2, = 12. To do this, we can do 12÷1 1/2 = 8.

Since there is 8 times the amount of flour used, there must be 8 times the amount of eggs used to keep the ingredients in proportion.

4 x 8 = 32

32 eggs would be used to make all the bread possible with 12 pounds of flour.

Answer 2

4 for every 1.5 pounds 

We can set up a proportion to solve for x (our needed eggs)

4/1.5 = x/12

Cross multiply

4*12=1.5x
48=1.5x
1.5x/1.5= 48/1.5

1.5 and 1.5 cross out and we are left with x on one side of our equation.

x= 48/1.5

Now we need to divide to solve for x.

48/1.5= 32

x=32

Our final answer is that for 12 pounds of flowers, we need 32 eggs.
