Let's go through the questions in the image one by one and solve them.

Part A: Fractions

1. What is $\frac{3}{8}$ added to $\frac{2}{8}$? $\frac{3}{8} + \frac{2}{8} = \frac{3+2}{8} = \frac{5}{8}$ Answer: $\frac{5}{8}$

2. What is the difference between $\frac{5}{12}$ and $\frac{3}{12}$? $\frac{5}{12} - \frac{3}{12} = \frac{5-3}{12} = \frac{2}{12} = \frac{1}{6}$ Answer: $\frac{1}{6}$

3. What will you get if you add $\frac{1}{4}$ to $\frac{2}{4}$? $\frac{1}{4} + \frac{2}{4} = \frac{1+2}{4} = \frac{3}{4}$ Answer: $\frac{3}{4}$

Part B: Integers

4. What is the result when $+4$ and $-3$ are added? $+4 + (-3) = 4 - 3 = 1$ Answer: 1

5. Give a number greater than -12. Answer: There are many possible answers, for example, 0.

6. Multiply 3 and $-6$. $3 \times (-6) = -18$ Answer: $-18$

7. What is the quotient when $-20$ is divided by $-4$? $\frac{-20}{-4} = 5$ Answer: 5

Part C: Decimals

Would you like further explanations or details on any of these questions?

Here are 5 related questions for practice:

1. What is $\frac{5}{6}$ minus $\frac{1}{6}$?
2. Multiply $\frac{3}{4}$ by $\frac{2}{3}$.
3. What is the result of adding $+6$ and $-9$?
4. Give a number less than $-5$.
5. Divide $15$ by $3$.

Tip: Always simplify fractions to their lowest terms if possible.
