$$\frac{ 4 }{ 5 } + \frac{ 19 }{ 20 }$$

$\frac{7}{4}=1.75$

Least common multiple of $5$ and $20$ is $20$. Convert $\frac{4}{5}$ and $\frac{19}{20}$ to fractions with denominator $20$.

$$\frac{16}{20}+\frac{19}{20}$$

Since $\frac{16}{20}$ and $\frac{19}{20}$ have the same denominator, add them by adding their numerators.

$$\frac{16+19}{20}$$

Add $16$ and $19$ to get $35$.

$$\frac{35}{20}$$

Reduce the fraction $\frac{35}{20}$ to lowest terms by extracting and canceling out $5$.

$$\frac{7}{4}$$

$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$
