Set up the multiplication problem.

Place the whole number over 1 to make it a fraction.

$\frac{15}{1} \cdot \frac{8}{5} \cdot \frac{14}{4}$

Use cross-cancelation to reduce the fractions before multiplying.

$\frac{\overset{3}{\cancel{15}}}{1} \cdot \frac{\overset{2}{\cancel{8}}}{\underset{1}{\cancel{5}}} \cdot \frac{14}{\underset{1}{\cancel{4}}}$

Multiply the numerators and then multiply the denominators.

$\frac{3}{1} \cdot \frac{2}{1} \cdot \frac{14}{1} = \frac{84}{1}$

Make sure that your answer is in simplest form.

$\frac{84}{1} = 84 \ \div\ 1 = 84$

Set up the multiplication problem.

You are asked to find the part of the carousel earnings that were collected from children's ride fees over 7 days.

Remember that by the commutative property of multiplication, you can multiply in any order you choose.

$\frac{420}{1} \cdot \frac{7}{1} \cdot \frac{3}{4}$

Use cross-cancelation to reduce the fractions before multiplying.

$\frac{\overset{105}{\cancel{420}}}{1} \cdot \frac{7}{1} \cdot \frac{3\phantom{0}}{\underset{1}{\cancel{4\phantom{0}}}}$

Multiply the numerators and then multiply the denominators.

$\frac{105}{1} \cdot \frac{7}{1} \cdot \frac{3}{1} = \frac{2205}{1}$

Make sure that your answer is in simplest form.

$\frac{2205}{1} = 2205 \ \div\ 1 = 2205$

To solve this problem, you need to set up three multiplication problems.

Dried Insects/Edible Flowers:

$\frac{1}{8} \cdot \frac{13}{1} \cdot \frac{7}{1}$

Mixed Fruits:

$\frac{1}{2} \cdot \frac{13}{1} \cdot \frac{7}{1}$

Green Beans:

$\frac{1}{4} \cdot \frac{13}{1} \cdot \frac{7}{1}$

There is no cross-canceling to be done within any of these multiplication problems.

Multiply the numerators and then multiply the denominators.

These fractions are all in simplest form. You can leave them as improper fractions, or you can divide them out.

Dried Insects/Edible Flowers:

$\frac{1}{8} \cdot \frac{13}{1} \cdot \frac{7}{1} = \frac{91}{8}$

Mixed Fruits:

$\frac{1}{2} \cdot \frac{13}{1} \cdot \frac{7}{1} = \frac{91}{2}$

Green Beans:

$\frac{1}{4} \cdot \frac{13}{1} \cdot \frac{7}{1} = \frac{91}{4}$

These fractions are all in simplest form. You can leave them as improper fractions, or you can divide them out to convert the improper fractions to mixed numbers.

Dried Insects/Edible Flowers:

$\frac{91}{8} = 91 \ \div\ 8 = 11 \textsf{ R}3 = 11\frac{3}{8}$ cups

Mixed Fruits:

$\frac{91}{2} = 91 \ \div\ 2 = 45 \textsf{ R}1 = 45\frac{1}{2}$ cups

Green Beans:

$\frac{91}{4} = 91 \ \div\ 4 = 22 \textsf{ R}3 = 22\frac{3}{4}$ cups
