The image contains several fraction multiplication problems. We need to solve problems number 2 and 4. Problem 2 is $\frac{7}{4} \times \frac{5}{6}$. Problem 4 is $6 \times \frac{2}{3}$.

1. Problem Description

The image contains several fraction multiplication problems. We need to solve problems number 2 and

4. Problem 2 is $\frac{7}{4} \times \frac{5}{6}$.

Problem 4 is $6 \times \frac{2}{3}$.

2. Solution Steps

For problem 2, we multiply the numerators and the denominators:

$\frac{7}{4} \times \frac{5}{6} = \frac{7 \times 5}{4 \times 6}$

$\frac{7 \times 5}{4 \times 6} = \frac{35}{24}$

For problem 4, we can rewrite 6 as a fraction $\frac{6}{1}$:

$6 \times \frac{2}{3} = \frac{6}{1} \times \frac{2}{3}$

Then, multiply the numerators and the denominators:

$\frac{6}{1} \times \frac{2}{3} = \frac{6 \times 2}{1 \times 3}$

$\frac{6 \times 2}{1 \times 3} = \frac{12}{3}$

Simplify the fraction:

$\frac{12}{3} = 4$

3. Final Answer

The answer to problem 2 is $\frac{35}{24}$.

The answer to problem 4 is $4$.
