Answer:
1) [tex]\frac{13}{4}[/tex]
2) [tex]\frac{11}{2}[/tex]
3) [tex]\frac{5}{3}[/tex]
4) [tex]\frac{35}{8}[/tex]
Step-by-step explanation:
we know that
A mixed number is the sum of a whole number and a fraction number
case 1) we have
[tex]3\frac{1}{4}[/tex]
so
[tex]3\frac{1}{4}=3+\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}[/tex]
case 2) we have
[tex]5\frac{1}{2}[/tex]
so
[tex]5\frac{1}{2}=5+\frac{1}{2}=\frac{5*2+1}{2}=\frac{11}{2}[/tex]
case 3) we have
[tex]1\frac{2}{3}[/tex]
so
[tex]1\frac{2}{3}=1+\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}[/tex]
case 4) we have
[tex]4\frac{3}{8}[/tex]
so
[tex]4\frac{3}{8}=4+\frac{3}{8}=\frac{4*8+3}{8}=\frac{35}{8}[/tex]
