Question

$$2.5 \times 4 - 25.5 \div 2.5 2$$

Evaluate

$-10.4$

Solution Steps

Multiply $2.5$ and $4$ to get $10$.

$$10-\frac{25.5}{2.5}\times 2$$

Expand $\frac{25.5}{2.5}$ by multiplying both numerator and the denominator by $10$.

$$10-\frac{255}{25}\times 2$$

Reduce the fraction $\frac{255}{25}$ to lowest terms by extracting and canceling out $5$.

$$10-\frac{51}{5}\times 2$$

Express $\frac{51}{5}\times 2$ as a single fraction.

$$10-\frac{51\times 2}{5}$$

Multiply $51$ and $2$ to get $102$.

$$10-\frac{102}{5}$$

Convert $10$ to fraction $\frac{50}{5}$.

$$\frac{50}{5}-\frac{102}{5}$$

Since $\frac{50}{5}$ and $\frac{102}{5}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{50-102}{5}$$

Subtract $102$ from $50$ to get $-52$.

$$-\frac{52}{5}$$

Factor

$-10.4$
