¾+2²/5 = .... Tolong di bantu ya terima kasih

Saya bantu jawab ya.

》 3/4 + 2 2/5 =

= 2 2/5 + 3/4
= 2 2×4/5×4 + 3×5/4×5
= 2 8/20 + 15/20
= 2 8+15/20
= 2 23/20
= 3 3/20

》 4/5 + 1 2/3 =

= 1 2/3 + 4/5
= 1 2×5/3×5 + 4×3/5×3
= 1 10/15 + 12/15
= 1 10+12/15
= 1 22/15
= 2 7/15

Semoga bisa membantu! :D
