Question

Estimate the quotient 430 divided by 9. Think basic multiplication facts to help find compatible numbers.

Answer 1

430 can be estimated to 400
9 can be estimated to 10
400 divided by 10 is 40
So the estimation would be 40
The exact would be 47.7

Answer 2

Answer:

Estimated value = 45

Step-by-step explanation:

Dividend = 430

Rounding off the dividend to nearest multiple of 50 = 450

Divisor = 9

Rounding off the divisor to nearest multiple of 10 = 10

Dividing the rounded off dividend by the rounded off divisor, we get the quotient as $\[\frac{450}{10}\]$

This is a simple division compared to the original problem and the qiotient turns out to be 45. Note that this is just an estimation of the actual value which can be computed to be  47.7.
