Hasil dhasil dari 1/2+3/4+2/5 adalah a

1/2 + 3/4 + 2/5 = 50/100 + 75/100 + 40/100 = 165/100 = 1 65/100 = 1 13/20
semoga membantu :)

[tex] \frac{1}{2} + \frac{3}{4} + \frac{2}{5} \\ = \frac{10}{20} + \frac{15}{20} + \frac{8}{20} \\ = \frac{25}{20} + \frac{8}{20} = \frac{33}{20} = 1 \frac{13}{20} [/tex]
