The rounded dividend would be 4.2
The rounded divisor would be 7.0
The rounded quotient would be 0.60
The exact quotient would be 0.57
Explanation:
In estimating it is helpful to round to compatible numbers.
look for a set of numbers will divide evenly.
42 is a multiple of 7 so this is a set of compatible numbers.
round 4.161 off to 4.2
round 7.3 off to 7.0
Both numbers have the same amount of significant digits.
Then divide to receive a good estimate of what the exact answer should be.
# 4.2/7.0 = 0.60 ( to two significant digits)
Use a calculator to find the exact answer.
