Question

1. estamate the sum

11/15+1/8
2 .use rounding to estimate the product
4 3/4 * 7 2/17
3. choose the sum
5/6 + 4/9
A. 1/2
B. 9/18
C. 1 5/18
D. 1 1/2

Answer 1

The sum for 11/15 + 1/8 = 103/120

The product for 4 3/4 * 7 2/17 = 33 55/68

The sum for 5/6 + 4/9 = 1 5/18

Hope that helps :)

Answer 2

Explanation:

1.
`(11)/(15)+(1)/(8)`

`(11)/(15)=0.733`

`(1)/(8)=0.125\approx 0`

`(11)/(15)+(1)/(8)=0.733+0.125\approx 1`

The estimated sum is 1.

2.
`(3)/(4) * 7(2)/(17)`

`(3)/(4)=0.75`

`7(2)/(17)=(121)/(17)=7.1176`

`(3)/(4) * 7(2)/(17)=0.75* 7.1176=5.3382\approx 5`

3.
`(5)/(6) + (4)/(9)`

`(5* 9+4* 6)/(6* 9)`

`(69)/(54)=(23)/(18)`

`(5)/(6) + (4)/(9)=(23)/(18)`
