Question 6. 61 × 68 ≈ ___ Answer: 4148 The estimation by rounding the answer is 4150.
Explanation: First, start with units first. So multiply 8 by 1. Then move on to the tens digit. So multiply 8 by 6. Continue the same process with digit 6. By multiplying both multiplicand 61 and multiplier 68, we get the value 4148.
Question 7. 79 × 56 ≈ ___ Answer: 4424 The estimation by rounding the answer is 4420.
Question 8. 392 × 46 ≈ ___ Answer: 18032 The estimation by rounding the answer is 18030.
Estimate by using compatible numbers. Show how you estimated.
Question 12. 33 × 84 ≈ ___ Answer: 2772.
Question 13. 450 × 21 ≈ ___ Answer: 9450
Question 14. 729 × 42 ≈ ___ Answer: 30618
Problem Solving
Explanation: Given The pounds of apples are 514 + 487 + 349 + 421 + 392 = 2163. The estimated answer is 2160.
Question 16. In one week, a campground rented 18 cabins at $225 each. About how much did they collect in rent altogether? Show how you estimated. Answer: $4050

Explanation: Given, The average weight for a guinea pig is 2 pounds. The average weight for a pot belly pig is 45 times greater than the guinea pig. So, 2 × 45 = 90 pounds.
Hot Problems
Explanation: Let us assume 34 and 17 are two whole numbers from the given digits. If we multiply 34 and 17 then the answer is 34 × 17 = 578. If we are rounding up to the nearest hundreds we will get 600. If we are rounding up the whole numbers the estimation of 34 to the nearest ten is 30 and 17 to the nearest ten is 20 Then the product is 30 × 20 = 600 Hence both the ways 34 and 17 are for the estimated product to be 600.
Question 19. ? Building on the Essential Question When is the estimation of products a useful tool? Answer: When the numbers we have are either bigger or smaller and when we buy multiple items which have the same price.
McGraw Hill My Math Grade 5 Chapter 2 Lesson 8 My Homework Answer Key
