Solve 4.8+4.8+4.5+2.5+2.5+2.0+4.0div7

$$4.8+4.8+4.5+2.5+2.5+2.0+4.0 \div 7$$

Evaluate

$$\frac{1517}{70}\approx 21.671428571$$

Solution Steps

Add 4.8 and 4.8 to get 9.6.

$$9.6+4.5+2.5+2.5+2+\frac{4}{7}$$

Add 9.6 and 4.5 to get 14.1.

$$14.1+2.5+2.5+2+\frac{4}{7}$$

Add 14.1 and 2.5 to get 16.6.

$$16.6+2.5+2+\frac{4}{7}$$

Add 16.6 and 2.5 to get 19.1.

$$19.1+2+\frac{4}{7}$$

Add 19.1 and 2 to get 21.1.

$$21.1+\frac{4}{7}$$

Convert decimal number 21.1 to fraction \frac{211}{10}.

$$\frac{211}{10}+\frac{4}{7}$$

Least common multiple of 10 and 7 is 70. Convert \frac{211}{10} and \frac{4}{7} to fractions with denominator 70.

$$\frac{1477}{70}+\frac{40}{70}$$

Since \frac{1477}{70} and \frac{40}{70} have the same denominator, add them by adding their numerators.

$$\frac{1477+40}{70}$$

Add 1477 and 40 to get 1517.

$$\frac{1517}{70}$$

Factor

$$\frac{37 \cdot 41}{2 \cdot 5 \cdot 7} = 21\frac{47}{70} = 21.67142857142857$$
