Answer:
[tex]93\frac{3}{20} \ square \ inches[/tex].
Step-by-step explanation:
Given:
Maggie has 4 3/5 container of icing to decorate cakes for a bake sale.
Each container will cover 20 1/4 square inches.
Question asked:
How many square inches will it cover if she uses all of her icing ?
Solution:
Total number of container Maggie has = [tex]4\frac{3}{5}[/tex]
Each container will cover = [tex]20\frac{1}{4}[/tex] square inches.
Now, we can find easily that how many square inches it will cover by using all of her icing by unitary method:
Each container will cover = [tex]20\frac{1}{4}[/tex]
[tex]4\frac{3}{5}[/tex] container will cover = [tex]20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5} \[/tex]
[tex]=\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches[/tex]
Thus, it will cover [tex]93\frac{3}{20} \ square \ inches[/tex] ,if she uses all of her icing.
