caranya :
n= 120% = 12/10
p= 14/5
jawab :
12/10 x 5/14
= 60/140 : 20
= 3/7
n = 120% = 12/10
p = 2 4/5 = 14/5
dicoba satu persatu
a. m × n = 6/7
10/7 × 12/10 = 12/7
pilihan a salah
b. m × p = 2
10/7 × 14/5 = 4
pilihan b salah
c. m ÷ p = 10/49
10/7 ÷ 14/5 = 10/7 × 5/14 = 50/98 = 25/49
pilihan c salah
d. n ÷ p = 3/7
12/10 ÷ 14/5 = 12/10 × 5/14 = 60/140 = 3/7
pilihan d benar
jawabannya adalah D. n ÷ p = 3/7
semoga membantu
