Solve 71/8+41/2-075

$$7 \frac { 1 } { 8 } + 4 \frac { 1 } { 2 } - 075$$

Evaluate

$$\frac{93}{8}=11.625$$

Solution Steps

Multiply 7 and 8 to get 56.

$$\frac{56+1}{8}+\frac{4\times 2+1}{2}-0\times 75$$

Add 56 and 1 to get 57.

$$\frac{57}{8}+\frac{4\times 2+1}{2}-0\times 75$$

Multiply 4 and 2 to get 8.

$$\frac{57}{8}+\frac{8+1}{2}-0\times 75$$

Add 8 and 1 to get 9.

$$\frac{57}{8}+\frac{9}{2}-0\times 75$$

Least common multiple of 8 and 2 is 8. Convert \frac{57}{8} and \frac{9}{2} to fractions with denominator 8.

$$\frac{57}{8}+\frac{36}{8}-0\times 75$$

Since \frac{57}{8} and \frac{36}{8} have the same denominator, add them by adding their numerators.

$$\frac{57+36}{8}-0\times 75$$

Add 57 and 36 to get 93.

$$\frac{93}{8}-0\times 75$$

Multiply 0 and 75 to get 0.

$$\frac{93}{8}-0$$

Subtract 0 from \frac{93}{8} to get \frac{93}{8}.

$$\frac{93}{8}$$

Factor

$$\frac{3 \cdot 31}{2 ^ {3}} = 11\frac{5}{8} = 11.625$$
