Question

$$90 \frac { 4 } { 5 } - 42 \frac { 1 } { 5 }$$

Evaluate

$\frac{243}{5}=48.6$

Solution Steps

Multiply $90$ and $5$ to get $450$.

$$\frac{450+4}{5}-\frac{42\times 5+1}{5}$$

Add $450$ and $4$ to get $454$.

$$\frac{454}{5}-\frac{42\times 5+1}{5}$$

Multiply $42$ and $5$ to get $210$.

$$\frac{454}{5}-\frac{210+1}{5}$$

Add $210$ and $1$ to get $211$.

$$\frac{454}{5}-\frac{211}{5}$$

Since $\frac{454}{5}$ and $\frac{211}{5}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{454-211}{5}$$

Subtract $211$ from $454$ to get $243$.

$$\frac{243}{5}$$

Factor

$\frac{3 ^ {5}}{5} = 48\frac{3}{5} = 48.6$
