Rewrite the mixed fractions as improper fractions, cross-cancel, and multiply across:

$\displaystyle \frac{5}{7} \cdot 1 \frac{1}{7} \cdot 2 \frac{4}{5} = \frac{5}{7} \cdot \frac{8}{7} \cdot \frac{14}{5}= \frac{1}{1} \cdot \frac{8}{7} \cdot \frac{2}{1}= \frac{16}{7}= 2\frac{2}{7}$

By order of operations, multiply first:

$\displaystyle 3.2 \times 1.5$

Multiply 32 by 15, and position the decimal point so that two digits are right of it:

$\displaystyle 32 \times 15 = 480$

$\displaystyle 3.2 \times 1.5 = 4.80 = 4.8$

Now add this product to 5.96:

$\displaystyle 5.96 + 3.2 \times 1.5 = 5.96 + 4.8$

Append a zero to the 4.8, and align the decimal points:

  $\displaystyle 5.96$

  $\displaystyle \underline{4.80}$

$\displaystyle 10.76$

By order of operations, multiply first:

$\displaystyle 1.4 \times 1.6$

Multiply 14 by 16, and position the decimal point so that two digits are right of it:

$\displaystyle 14 \times 16 = 224$

$\displaystyle 1.4 \times 1.6 = 2.24$

Now add this product to 6.5:

$\displaystyle 6.5 + 1.4 \times 1.6 = 6.5 + 2.24$

Append a zero to the 6.5, and align the decimal points:

$\displaystyle 6.50$

$\displaystyle \underline{2.24}$

$\displaystyle 8.74$

When multiplying a fraction, simply multiply straight across - numerator times numerator, denominator times denominator. When you do that, you should get this answer:

$\displaystyle \tfrac{3}{5} \times \tfrac{1}{6} = \tfrac{3}{30}$

Do not forget to reduce. 3 and 30 can both be evenly divided by 3, which would give you $\displaystyle \tfrac{1}{10}$ as your answer.

First, multiply the numbers, ignoring the decimal points:

$\displaystyle 58 \times 83 = 4814$

Since the two factors in the original product have three digits to the right of the decimal points between them, position the decimal point in the product such that three digits are at its right. The result, therefore, is 

$\displaystyle 4.814$

First, remove the decimal points, multiplying as follows:

$\displaystyle 673 \times 6 = 4 038$

Between them, the two factors have five digits to the right of their decimal points, so position the decimal point in the product so that there are five digits to the right. This will require placing a zero in front as a placeholder, so the final result is 

$\displaystyle 6.73 \times 0.006 = 0.04038$

To find the product of two fractions, multiply the numerators together and then multiply the denominators together.

$\displaystyle \frac{3}{5}\cdot \frac{7}{9}=\frac{21}{45}$, which can be reduced to $\displaystyle \frac{7}{15}$.

To find the product of two fractions, multiply the numerators together and then multiply the denominators together.

$\displaystyle \frac{5}{7}\cdot \frac{3}{4}=\frac{15}{28}$

Multiply the numerators together, and then multiply the denominators together:

$\displaystyle \frac{1}{3} \times \frac{4}{5}=\frac{1\times 4}{3\times 5}=\frac{4}{15}$

To solve for this expression, first multiple the numerators, and then multiply the demonators. 

$\displaystyle \frac{4}{5}\cdot\frac{7}{8}$

$\displaystyle \frac{4\times7}{5\times8}$

$\displaystyle \frac{28}{40}$

Simplify the fraction by removing a common factor.

$\displaystyle \frac{28\div4}{40\div4}=\frac{7}{10}$
