Question

Nia has the total weight of her luggage to be no more than 50 kilograms. She has three suitcases that weigh 15.8 kilograms, 17.42 kilograms, and 16.28 kilograms. Is the total weigh within the limit? Use only estimation to decide. Explain how you know your estimate gives you the correct answer.

Answer 1

Yes

Explanation:

First round the numbers. If the digit before the starting is over 5, round it up. If it is smaller then the number stays. Here is an example: 15.8 will become 16. 17.42 becomes 17. 16.28 becomes 16. Now add your rounded numbers. 16+17+16= 49.

This is just below 50 so your answer is a yes
