Estimate the answers to the following problems. Check your answer by using the opposite operation.
Question 1.
There are 527 sixth-grade students who will take a field trip. There are 9 buses. About how many students will be riding in each bus?
Round 527 to ___.
About ____ students will ride each bus.
Answer:
Number of students will be riding in each bus = 59.
Explanation:
Number of sixth-grade students who will take a field trip = 527.
Number of buses = 9.
Number of students will be riding in each bus = Number of sixth-grade students who will take a field trip ÷ Number of buses
= 527 ÷ 9
= 58.56
=> Dividing 527 by 9, we get 58 as quotient and 5 as remainder.
= Rounded to 59.
= Divi
Question 2.
At West Side Middle School, there are 42 classrooms with 28 desks in each. About how many desks are there?
There are about ____ desks.
Answer:
Total number of desks = 1,176.
There are about 1,176 desks.
Explanation:
Number of classrooms at West Side Middle School = 42.
Number of desks at West Side Middle School in each = 28.
Total number of desks = Number of classrooms at West Side Middle School × Number of desks at West Side Middle School in each
= 42 × 28
= 1,176.
Question 3.
There are 563 books to be shelved in the library. Each shelf holds 7 books. About how many shelves will be used?
Round 563 to _____.
About ___________ shelves will be used.
Answer:
Number of shelves will be used = 81.
About 81 shelves will be used.
Explanation:
Number of books to be shelved in the library = 563.
Number of books each shelf holds = 7.
Number of shelves will be used = Number of books to be shelved in the library ÷ Number of books each shelf holds
= 563 ÷ 7
= 80.42.
=> Dividing 563 by 7, we get 80 as quotient and 3 as remainder.
= Rounded to 81.
Question 4.
Mrs. Juergen’s class is building a model city from craft sticks. Each house requires 267 sticks. The class will build 93 houses. About how many sticks will be needed?
About ____ sticks will be needed.
Answer:
Number of sticks will be needed = 24,831.
About 24,831 sticks will be needed.
Explanation:
Number of sticks each house requires = 267.
Number of house the class will build = 93.
Number of sticks will be needed = Number of sticks each house requires × Number of house the class will build
= 267 × 93
= 24,831.
Question 5.
Thirty-eight students are going on a field trip. Parents will drive. Each car can hold ‘4students along with the driver. How many cars will be needed?
Round 38 to ____.
About __________ cars will be needed.
Answer:
Number of cars will be needed = 10.
Explanation:
Number of students going on a field trip = 38.
Number of students each car can hold along with the driver = 4.
Number of cars will be needed = Number of students going on a field trip ÷ Number of students each car can hold along with the driver
= 38 ÷ 4
= 9.5
=> Dividing 38 by 4, we get 9 as quotient and 2 as remainder.
= Rounded to 10.
Question 6.
