Answer:
30 3/8 pounds of shortening used.
Step-by-step explanation:
20 1/2 + 29 3/4 +18 1/8 + 16 + 5 1/4 = 89.625
120- 89.625 = 30.375 pounds
0.375 as a fraction = 3/8 + 30
Therefore the total shortening used = 30 3/8 pounds
How many pounds of shortening are used in this cake mix is maximum figure as we found exact 0.375
We can do this by multiplying the 0.375 x 2 = 0.750 = 3/4
Then counteracting 4 = 1 to 8 = 1 and keeping the top fraction.
1/2 of 3/4 = 3/8
3/8 x 2 = 0.75
0.75 /2 = 0.375
