Question

What is a reasonable estimate for 1 3/4+ 1 1/4+ 1/16

Answer 1

13/4 rounds to about 3, 11/4 rounds to 3, and 1/16 rounds to 0. So a resonable estimate would be about 6.

Answer 2

`1(3)/(4)` +
`(11)/(4)` +
`(1)/(16)`
1st step: Change the mixed fractions to improper fractions:

`1(3)/(4)` =
`(7)/(4)`
2nd step: Find a common denominator
16 is the common denominator

`(7*4)/(4*4)` +
`(11*4)/(4*4)` +
`(1)/(16)`
=
`(28+44+1)/(16)`
=
`(73)/(16)`
As a mixed fraction:
=
`4(9)/(16)`
