Question

$$5 \frac { 1 } { 5 } - \frac { 3 } { 4 }$$

$\frac{89}{20}=4.45$

Multiply $5$ and $5$ to get $25$.

$$\frac{25+1}{5}-\frac{3}{4}$$

Add $25$ and $1$ to get $26$.

$$\frac{26}{5}-\frac{3}{4}$$

Least common multiple of $5$ and $4$ is $20$. Convert $\frac{26}{5}$ and $\frac{3}{4}$ to fractions with denominator $20$.

$$\frac{104}{20}-\frac{15}{20}$$

Since $\frac{104}{20}$ and $\frac{15}{20}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{104-15}{20}$$

Subtract $15$ from $104$ to get $89$.

$$\frac{89}{20}$$

$\frac{89}{2 ^ {2} \cdot 5} = 4\frac{9}{20} = 4.45$
