Solve (7div2)+(7div2)+(7div2)+(0.6div2)

$$(7 \div 2)+(7 \div 2)+(7 \div 2)+(0.6 \div 2)$$

Evaluate

$$10.8$$

Solution Steps

Since \frac{7}{2} and \frac{7}{2} have the same denominator, add them by adding their numerators.

$$\frac{7+7}{2}+\frac{7}{2}+\frac{0.6}{2}$$

Add 7 and 7 to get 14.

$$\frac{14}{2}+\frac{7}{2}+\frac{0.6}{2}$$

Since \frac{14}{2} and \frac{7}{2} have the same denominator, add them by adding their numerators.

$$\frac{14+7}{2}+\frac{0.6}{2}$$

Add 14 and 7 to get 21.

$$\frac{21}{2}+\frac{0.6}{2}$$

Expand \frac{0.6}{2} by multiplying both numerator and the denominator by 10.

$$\frac{21}{2}+\frac{6}{20}$$

Reduce the fraction \frac{6}{20} to lowest terms by extracting and canceling out 2.

$$\frac{21}{2}+\frac{3}{10}$$

Least common multiple of 2 and 10 is 10. Convert \frac{21}{2} and \frac{3}{10} to fractions with denominator 10.

$$\frac{105}{10}+\frac{3}{10}$$

Since \frac{105}{10} and \frac{3}{10} have the same denominator, add them by adding their numerators.

$$\frac{105+3}{10}$$

Add 105 and 3 to get 108.

$$\frac{108}{10}$$

Reduce the fraction \frac{108}{10} to lowest terms by extracting and canceling out 2.

$$\frac{54}{5}$$

Factor

$$\frac{2 \cdot 3 ^ {3}}{5} = 10\frac{4}{5} = 10.8$$
