Question

A bag contains 25 kg of flour. A baker used 80% of it to bake bread. How much flour,in kg,remained ?​

Answer 1

25 - 20 = 5 kg

Steps:

25×80/100 = 25×8/10 = 200/10 = 20 kg

25 - 20 = 5 kg

Answer 2

5 kg flour remains

Explanation:

80% of the original 25 kg comes to 0.80(25 kg), or 20 kg. We convert 80% to its decimal equivalent, 0.80, to get this result

The amount of flour remaing is then (1.00 - 0.80)(25 kg), or 0.20(25 kg) = 5 kg.

5 kg flour remains.
