Question

Dinda mempunyai 1/5 m pita kemudian membli lagi 3 3/4 m lalu memberikan pada salma 2 7/8 ,berapa meter pita dinda sekarang ?

Answer 1

(1/5 + 15/4 )- 23/8
= (8/40 + 150/40) - 115/40
=158/40 - 115/40
= 43/40

Answer 2

Pita linda = 1/5 + 3 3/4 - 2 7/8
= (1/5 + 3 3/4)- 2 7/8
= 3(4/20 + 15/20) - 2 7/8
= 3 19/20 - 2 7/8
= (3 - 2) + (19/20 - 7/8)
= 1 + (38/40 - 35/40)
= 1 3/40
