Abakery uses 10 4/5 oz of icing for every 1/4 of a cake what is the unit rate in ounces of icing for cake

1 whole cake= 1/4 + 1/4 + 1/4 + 1/4
1/4= 0.25

So we multiply 10 4/5oz per 1/4 cake by four to find out how many ounces are needed for 1 whole cake.

T= total ounces for 1 whole cake
T= (1 ÷ cake portion)(# ounces)
T= (1/0.25)(10 4/5)
change mixed fraction to improper
T= (4)(54/5)
multiply 4 by the numerator
T= (4*54)/5
T= 216/5 ounces for whole cake

T= 43 1/5 ounces for whole cake

Hope this helps! :)
