kelereng A=1 1/2 kelereng B=1 1/3 kelereng C.jika kelereng A=42 butir,tentukan jumlah kelereng mereka.TOLONG PAKAI CARANYA

Ans :

Diketahui
Kelereng A
= 1½
= ( 2 x 1 ) + 1
= 2 + 1
= 3/2

Kelereng B
= 1⅓
= ( 3 x 1 ) + 1
= 3 + 1
= 4/3

Kelereng A
= 42 butir

Ditanya
Jumlah kelereng masing-masing = ... ?


Penyelesaian :

Kelereng A
= 3/2 x 42
= ( 42 ÷ 2 ) x 3
= 21 x 3
= 63

Kelereng B
= 4/3 x 42
= ( 42 ÷ 3 ) x 4
= 14 x 4
= 56

I HOPE THIS HELPS
