Q14:
Maged wants to estimate the value of . He knows that is 3.14 to two decimal places but decides to round this to the nearest whole number to make this estimate easier to calculate.
What will his estimate of be?
Maged wants to check whether his approximation is accurate to the nearest whole number, so he rounds to 3.1. What will his approximation of be now?
Hence, what is an approximation of accurate to the nearest whole number?
Q15:
