Question

If in a school 80 students are eating 12kg rice, then 100 students will eat how much kg of rice? Answer briefly with proper methods.​

Answer 1

Answer:

Weight of rice eaten by 80 students =12kg

Weight of rice eaten by 1 student =12/80

Therefore, kgs of rice eaten by 100 students =100*12/80

=12/4

=3kgs

Answer 2

Answer:

15kg

Explanation:

80 students eating 12kg of rice can be expressed as a ratio:

80 : 12

If 100 students eat rice according to the same ratio, then calculate 100 ÷ 80 , then multiply it with 12:

100 ÷ 80 = 1.25

12 * 1.25 = 15

100 student would therefore eat 15kg of rice.
