3/4×5adalah 5/6-1/3adalah 21/2+22/3adalah

[tex] \frac{3}{4} \times 5 = \frac{15}{4 } \\ \frac{5}{6} - \frac{1}{3} = \frac{5}{6} - \frac{2}{6} = \frac{3}{6} \\ \frac{21}{2} + \frac{22}{3} = \frac{63}{6} + \frac{44}{6} = \frac{105}{6} [/tex]
kalo salah maaf ya...

1.3,75
2.1/2
3.17,83

semoga membantu yaa
