Answer: 3 1/4 + 2 1/4 + 1 1/12=7
Step-by-step explanation:
Multiply 3 times 4 to get 12
[tex]\frac{12+1}{4} + \frac{2x4+1}{4} + \frac{1x2+1}{2}[/tex]
Add 12+1=13
[tex]\frac{13}{4} + \frac{2x4+1}{4} +\frac{1x2+1}{2}[/tex]
multiply 2 times 4 get 8
[tex]\frac{13}{4} +\frac{8+1}{4} +\frac{1x2+1}{2} \\\frac{13}{4} + \frac{9}{4} +\frac{1x2+1}{2}[/tex]
Add 13 plus to get 22
[tex]\frac{22}{4} +\frac{1x2+1}{2}[/tex]
[tex]\frac{11}{2} +\frac{1x2+1}{2}[/tex]
Multiply 1 times 2 to get 2
[tex]\frac{11}{2} +\frac{2+1}{2}[/tex]
Add 2 plus 1 to get 3
[tex]\frac{11}{2} +\frac{3}{2}[/tex]
[tex]\frac{11+3}{2}[/tex]
Add 11 and 3 to get 14.
[tex]\frac{14}{2}[/tex]
divide 14 by 2
to get 7
