Solve 2.5+(-3.7)*2+93/5=

$$2.5+(-3.7) \times 2+9 \frac{ 3 }{ 5 } =$$

Evaluate

$$4.7$$

Solution Steps

Multiply -3.7 and 2 to get -7.4.

$$2.5-7.4+\frac{9\times 5+3}{5}$$

Subtract 7.4 from 2.5 to get -4.9.

$$-4.9+\frac{9\times 5+3}{5}$$

Multiply 9 and 5 to get 45.

$$-4.9+\frac{45+3}{5}$$

Add 45 and 3 to get 48.

$$-4.9+\frac{48}{5}$$

Convert decimal number -4.9 to fraction -\frac{49}{10}.

$$-\frac{49}{10}+\frac{48}{5}$$

Least common multiple of 10 and 5 is 10. Convert -\frac{49}{10} and \frac{48}{5} to fractions with denominator 10.

$$-\frac{49}{10}+\frac{96}{10}$$

Since -\frac{49}{10} and \frac{96}{10} have the same denominator, add them by adding their numerators.

$$\frac{-49+96}{10}$$

Add -49 and 96 to get 47.

$$\frac{47}{10}$$

Factor

$$\frac{47}{2 \cdot 5} = 4\frac{7}{10} = 4.7$$
