Question

1. Diana ordered 1 5/8 pounds of birdseed for Mango. She also ordered 1 3/4 pounds of treats for her parrot. a. How many pounds of birdseed and treats did she order in all?

Answer 1

Pounds of birdseed = 1 5/8

Pounds of treats = 1 3/4

To add them, first write them in simple fraction form:

1 5/8 = (1x8+5) / 8 = 13/8

1 3/4 = (1x4+3) /4 = 7/4

`(13)/(8)+(7)/(4)`

To add simple fractions both must have the same denominator (the bottom number)

So, we have to multiply 7/4 by 2/2

`(13)/(8)+((7)/(4)\cdot(2)/(2))`
`(13)/(8)+(14)/(8)`
`(27)/(8)`
