Question

Li needs to buy 2 kilograms of apples. If she buys 9 apples that each weigh approximately 150 grams, will she have enough? Explain.

Answer 1

1 apple weighs 150 grams.
To find how much 9 apples weight, multiply the unit weight of the apples by 9.
150 • 9 = 1350
9 apples weight 1,350 grams.

There are 1,000 grams in a kilogram.
1 gram = 0.001 kilogram.
1350 grams = 1.35 kilograms

If Li needs 2 kilograms of apples, then 9 apples are not enough because 1.35 kilograms is less than 2 kilograms.
