Question

1. increase 160 yds by 10%
2. increase 6 inches by 10%
3. increase 5 inches by 20%
4. increase 140 yds by 30%
5. increase 76 oz by 75%

Explanation:

Problem 2: Increase 160 yds by 10%

Step1: Find 10% of 160

To find 10% of a number, we multiply the number by \( \frac{10}{100} = 0.1 \). So, \( 160 \times 0.1 = 16 \).

Step2: Add to the original number

Now, we add this increase to the original number 160. So, \( 160 + 16 = 176 \).

Step1: Calculate 10% of 6

10% of 6 is \( 6 \times 0.1 = 0.6 \).

Step2: Add to 6

Adding the increase to 6 gives \( 6 + 0.6 = 6.6 \).

Step1: Find 20% of 5

20% of 5 is \( 5 \times 0.2 = 1 \).

Step2: Add to 5

Adding the increase to 5 gives \( 5 + 1 = 6 \).

Answer:

176 yds

Problem 4: Increase 6 inches by 10%
