Question

Banyaknya pensil nana 1 2/3 pensil wati. Bila selisih pensil mereka 8 buah, jumlah pensil nana adalah

Answer 1

1  2/3 = 5/3

N = 5/3 W

N      - W = 8
5/3W - 3/3W = 8
2/3W = 8
W = 8 x 3/2 = 12 buah
N(nana) = 5/3W = 5/3(12)= 20 buah

Answer 2

Nana = n
wati = w
n = 1 2/3 w = 5/3 w
n-w = 8
n = ?

=> n - w = 8
=> 5/3 w - w  = 8
=> 2/3 w = 8
=> w = 8 x 3/2
=> w = 12
=> n = 5/3 w
=> n = 5/3 x 12
=> n = 20 buah
