$$\frac{3}{4}+\frac{4}{5}+\frac{3}{8}$$

$\frac{77}{40}=1.925$

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

$$\frac{15}{20}+\frac{16}{20}+\frac{3}{8}$$

Since $\frac{15}{20}$ and $\frac{16}{20}$ have the same denominator, add them by adding their numerators.

$$\frac{15+16}{20}+\frac{3}{8}$$

Add $15$ and $16$ to get $31$.

$$\frac{31}{20}+\frac{3}{8}$$

Least common multiple of $20$ and $8$ is $40$. Convert $\frac{31}{20}$ and $\frac{3}{8}$ to fractions with denominator $40$.

$$\frac{62}{40}+\frac{15}{40}$$

Since $\frac{62}{40}$ and $\frac{15}{40}$ have the same denominator, add them by adding their numerators.

$$\frac{62+15}{40}$$

Add $62$ and $15$ to get $77$.

$$\frac{77}{40}$$

$\frac{7 \cdot 11}{2 ^ {3} \cdot 5} = 1\frac{37}{40} = 1.925$
