Name Lesson 4.1 Reteach _ Estimate Quotients Using Multiples of 142 + 5 is between. Then Find two numbers the quotient estimate the quotient. You can use multiples to estimate. A multiple of a number is the product of a number and a counting number. Step 1 Think: What number multiplied by 5 is about 142? Since 142 is greater than 10 x 5, or 50, use counting numbers 10,20,30, and so on to find multiples of 5. Step 2 Multiply 5 by multiples of 10 and make a table. Counting Number 10 20 30 40 Multiple of 5 50 100 150 200 Step 3 Use the table to find multiples of 5 closest to 142. 20 x 5 = 100 30 x 5 = 150 +- 142 is between 100 and 150 . 142 is closest to 150 , so 142 --;-5 is about Find two numbers the quotient estimate the quotient. 1. is between.
