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?

Sagot :

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

[tex]\frac{13}{8}+\frac{7}{4}[/tex]

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

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

[tex]\frac{13}{8}+(\frac{7}{4}\cdot\frac{2}{2})[/tex][tex]\frac{13}{8}+\frac{14}{8}[/tex][tex]\frac{27}{8}[/tex]
