Question

Estimate each sum using front end estimation and then rounding 75 + 22

Answer 1

75+22= 97 estimated= 100
therefore , estimate from there.
9 is greater and 7 is greater so you’d go up. 100 would be the answer i think. but if you need help with the 75 estimated and 22 estimated it’ll be ...

22 = estimated =20
80+20= 100.
100 is the answer.
