Solve the following math problems: Q35: 3/8 * 240, Q36: 4 3/7 - 1 1/6

$$\frac{720}{8} = 90$$

The answer is $\boxed{\text{90}}$.

$$4\frac{3}{7} = \frac{(4 \times 7) + 3}{7} = \frac{28 + 3}{7} = \frac{31}{7}$$ $$1\frac{1}{6} = \frac{(1 \times 6) + 1}{6} = \frac{6 + 1}{6} = \frac{7}{6}$$

The expression becomes:

$$\frac{31}{7} - \frac{7}{6}$$

The least common multiple of 7 and 6 is 42.

$$\frac{31}{7} = \frac{31 \times 6}{7 \times 6} = \frac{186}{42}$$ $$\frac{7}{6} = \frac{7 \times 7}{6 \times 7} = \frac{49}{42}$$

$$\frac{137}{42} = 3 \text{ with a remainder of } 137 - (3 \times 42) = 137 - 126 = 11$$

So, the mixed number is $3\frac{11}{42}$.
The answer is $\boxed{3\frac{11}{42}}$.
