Answer: There are 20 girls
Explanation:
- 100% is the same as your original or total number → in this case, 100% is 50 students
- The first step is to work out 10%
→ Since 10% is the same as 100% divided by 10, we divide our original number (50) by 10.
50 ÷ 10 = 5
So, now we know that 10% of 50 is 5
- To calculate what 40% of 50 would be, we just multiply 10% by 4
5 x 4 is 20
Therefore, 40% of 50 students is 20.
