Question

Susie tries to read 50 pages of her book every day.

One week (7 days) she only managed to read 280 pages.

Answer 1

Answer: 25%

Explanation:

Approximate value = 350

Exact value = 280

The percentage error will be calculated by using the formula:

= (Approximate value - Exact value). Exact value × 100

= (350 - 280) / 280 × 100

= 70/280 × 100.

= 1/4 × 100

= 25%
