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]
