Solve 17/8+28/8+48/8

$$1 \frac { 7 } { 8 } + 2 \frac { 8 } { 8 } + 4 \frac { 8 } { 8 }$$

Evaluate

$$\frac{79}{8}=9.875$$

Solution Steps

Multiply 1 and 8 to get 8.

$$\frac{8+7}{8}+\frac{2\times 8+8}{8}+\frac{4\times 8+8}{8}$$

Add 8 and 7 to get 15.

$$\frac{15}{8}+\frac{2\times 8+8}{8}+\frac{4\times 8+8}{8}$$

Multiply 2 and 8 to get 16.

$$\frac{15}{8}+\frac{16+8}{8}+\frac{4\times 8+8}{8}$$

Add 16 and 8 to get 24.

$$\frac{15}{8}+\frac{24}{8}+\frac{4\times 8+8}{8}$$

Since \frac{15}{8} and \frac{24}{8} have the same denominator, add them by adding their numerators.

$$\frac{15+24}{8}+\frac{4\times 8+8}{8}$$

Add 15 and 24 to get 39.

$$\frac{39}{8}+\frac{4\times 8+8}{8}$$

Multiply 4 and 8 to get 32.

$$\frac{39}{8}+\frac{32+8}{8}$$

Add 32 and 8 to get 40.

$$\frac{39}{8}+\frac{40}{8}$$

Since \frac{39}{8} and \frac{40}{8} have the same denominator, add them by adding their numerators.

$$\frac{39+40}{8}$$

Add 39 and 40 to get 79.

$$\frac{79}{8}$$

Factor

$$\frac{79}{2 ^ {3}} = 9\frac{7}{8} = 9.875$$
