Penyelesaian :
No 1
7,2 - 3,19 = 4,01

No 2
[tex]\frac{4}{9} - \frac{3}{9} \\ = \frac{1}{9} [/tex]

No 3
[tex] \frac{3}{5} + 0.67 + 45\% \\ = \frac{3}{5} + \frac{67}{100} + \frac{45}{100} \\ = \frac{60}{100} + \frac{67}{100} + \frac{45}{100} \\ = \frac{172}{100} = 1 \frac{72}{100} = 1 \frac{18}{25} [/tex]

No 4
[tex] \frac{3}{4} = \frac{3}{4} \times 100 = 75\%[/tex]

No 5
[tex]2 \frac{3}{4} = \frac{11}{4} = 11 \div 4 = 2.75[/tex]

Good Luck ^^
