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.

Answer 2

This question is based on unit concept. Therefore, Li needs 2 kilograms of apples, then 9 apples are not enough because 1.35 kilograms is less than 2 kilograms.

Given:

Li needs to buy 2 kilograms of apples. If she buys 9 apples that each weigh approximately 150 grams.

According to the question,

It is given that, 1 apple =  150 grams

Now, find the weight of 9 apples,

$150 \times 9 = 1350 \, grams$

As we know that,

1 gram = 0.001 kilogram

1350 grams = 1.35 kg

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