Question

Maggie has 4 3/5 of icing to decorate cakes for a bake sale. Each container will cover 20 1/4 in2. How many square inches will it cover if she uses all of her icing.

Answer 1

Answer:

$93\frac{3}{20} \ square \ inches$.

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 = $4\frac{3}{5}$

Each container will cover = $20\frac{1}{4}$ 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 = $20\frac{1}{4}$

$4\frac{3}{5}$ container will cover = $20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5}$

                                                        $=\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches$

Thus,  it will cover $93\frac{3}{20} \ square \ inches$ ,if she uses all of her icing.
