Question

Mia buys a 5 lb bag of flour. If the bag weighs 4 lb, how much flour is left? Express your answer as a fraction, decimal, and percent.

Answer 1

To determine how much flour is left, subtract the weight of the bag from the total weight of the bag of flour. There is 1 lb of flour left, which is 1/5, 0.20 lb, or 20% of the original flour.

Step-by-step explanation:

To determine how much flour is left, we need to subtract the weight of the bag from the total weight of the bag of flour.

1. Let's start by subtracting the weight of the bag, which is 4 lb, from the total weight of the bag of flour, which is 5 lb.
2. 5 lb - 4 lb = 1 lb.

Therefore, there is 1 lb of flour left in the bag.

Expressed as a fraction, there is 1/5 of the original flour remaining.

Expressed as a decimal, there is 0.2 (or 0.20) lb of flour left.

Expressed as a percent, there is 20% of the original flour remaining.
