Sample Questions and Solutions
To provide a clearer understanding of how to approach questions from Chapter 30, here are a few sample questions along with their solutions.
Sample Question 1: Fractions
Question: Add \( \frac{1}{4} + \frac{2}{4} \).
Solution:
1. Find a common denominator, which is 4.
2. Add the numerators: \( 1 + 2 = 3 \).
3. The answer is \( \frac{3}{4} \).
Sample Question 2: Decimals
Question: Subtract \( 3.5 - 1.2 \).
Solution:
1. Align the decimal points:
```
3.5
- 1.2
```
2. Subtract:
\( 3.5 - 1.2 = 2.3 \).
Sample Question 3: Ratios
Question: The ratio of cats to dogs is 3:2. If there are 12 cats, how many dogs are there?
Solution:
1. Set up the ratio \( \frac{cats}{dogs} = \frac{3}{2} \).
2. Let the number of dogs be \( d \). Then, \( \frac{12}{d} = \frac{3}{2} \).
3. Cross-multiply: \( 3d = 24 \).
4. Solve for \( d \): \( d = 8 \). Therefore, there are 8 dogs.
