Question

1. Priya evaluates 218 ÷ 31 using a calculator and
she says that the answer is 70.3. Without doing
the actual calculation, use estimation to determine
whether Priya's answer is reasonable. Then use a
calculator to evaluate 218 ÷ 31. Is your estimated
value close to the actual value?




any body plz solve this with explaunation will be thankfull its urgent​

Answer 1

Answer:

No, Priya's value is not reasonable. The reason being that, the value of quotient cannot be in tens since both the numbers have lesser difference. Sinply we can estimate that the value will be close to 7 because since 31 is a tens number and 218 is a hundreds number. The actual approximate value when 218 ÷ 31 is 7.03225806452.

Answer 2

Answer:

Step-by-step explanation:

218 ≅ 210

31≅30

210/30

Estimation =7

Actual value: 218/31=7.03

Priya's answer isn't reasonable

Yes, estimated value is close to the actual value
