Question

Ariane wants to estimate 197.6 ÷ 5.48. Which number sentence shows the best way to estimate this quotient?

100 ÷ 5 = 20
100 ÷ 10 = 10
200 ÷ 5 = 40
200 ÷ 10 = 20

Answer 1

the answer is C. this is because if you round 197.6 it goes to 200. if you round 5.48 it is 5. thus 200/5 is what you would use
