Question

$$2\frac{4}{5}+\frac{1}{2}\times\frac{3}{4}$$

Evaluate

$\frac{127}{40}=3.175$

Solution Steps

Multiply $2$ and $5$ to get $10$.

$$\frac{10+4}{5}+\frac{1}{2}\times \frac{3}{4}$$

Add $10$ and $4$ to get $14$.

$$\frac{14}{5}+\frac{1}{2}\times \frac{3}{4}$$

Multiply $\frac{1}{2}$ times $\frac{3}{4}$ by multiplying numerator times numerator and denominator times denominator.

$$\frac{14}{5}+\frac{1\times 3}{2\times 4}$$

Do the multiplications in the fraction $\frac{1\times 3}{2\times 4}$.

$$\frac{14}{5}+\frac{3}{8}$$

Least common multiple of $5$ and $8$ is $40$. Convert $\frac{14}{5}$ and $\frac{3}{8}$ to fractions with denominator $40$.

$$\frac{112}{40}+\frac{15}{40}$$

Since $\frac{112}{40}$ and $\frac{15}{40}$ have the same denominator, add them by adding their numerators.

$$\frac{112+15}{40}$$

Add $112$ and $15$ to get $127$.

$$\frac{127}{40}$$
