Usually i tell my students to use benchmark fractions (1/2, 1/3, 1/4, 1/10) to do estimation problems but i am a little confused at how they arrived at the estimation for the problem given. Please help!!
Problem: 1  4/9  1/5  1/4
Estimation: 1  2/5  1/5  1/5
Another one
Problem: 5 and 23/32  3 and 7/16
Estimation: 5 and 3/4  3 and 1/2
