40%×dua satu per tiga dikurang tiga per sembilan

Answer 1

40% =40/100=4/10=2/5
21/3=7/1
3/9=1/3

2/5x7/1=14/5-1/3
=42/15 - 5/15 =37/15 =2 7/15

Answer 2

= 40/100 kali 21/3
= 40/100 kali 7/1 =280/100 : 20/20 = 14/5 = 2 4/5

= 2 4/5 = 14/5
= 14/5 - 3/9 = 126/45 - 15/45 = 111 /45 = 2 21/45 : 3/3 =2 7/15
