Question

After strict action by the government, the number of child labour declined from 12.6 million in 2001 to 4.35 million in 2011. This means that the child labour declined by _____ %.​

Answer 1

Answer:

Decline % = (12.6 - 4.35 / 12.6) × 100

= 8.25/ 12.60 × 100

= 825/1260 × 100

= 65.47 %

Explanation:

$\frac{12.6 - 4.35}{12.6} \times 100$
