8. Use compatible numbers to solve the problem 488 ÷ 62. (1 point)
450 ÷ 50 = 9
434 ÷ 62 = 7
490 ÷ 70 = 7
480 ÷ 60 = 8
If you do closest rounding, then that would be 490/60
So I guess C or D would be the likely choice.
Both 488 and 62 are 8 away from those ideal values, so use your class guidelines to choose.
Thx!
To use compatible numbers to solve the problem 488 ÷ 62, we can round the numbers to more manageable numbers that are easy to divide mentally.
Step 1: Round the dividend (488) to the nearest tens place. Since 488 is closer to 490, we can round it to 490.
Step 2: Round the divisor (62) to the nearest tens place. Since 62 is closer to 60, we can round it to 60.
Step 3: Divide the rounded numbers. 490 ÷ 60 = 8.
So the correct option from the given choices is "480 ÷ 60 = 8".
