Estimating Quotients and Rounding

The video tutorial explains how to estimate quotients by rounding numbers to the nearest ten and then dividing. It provides two examples: one with the numbers 156 and 17, and another with 522 and 13. For each example, the estimated quotient is calculated by rounding the numbers and dividing, followed by finding the actual quotient through direct division.

What is the first step in estimating a quotient?

• Divide the numbers directly

• Round the numbers to the nearest ten

• Multiply the numbers

• Subtract the numbers

Why do we round numbers when estimating quotients?

• To make numbers smaller

• To make numbers larger

• To increase accuracy

• To make division easier

What is the purpose of estimating a quotient?

• To avoid division

• To get a rough idea of the answer

• To make numbers smaller

• To find the exact answer
