Question

Diketahui pecahan m =1 3/7,n=120%,dan p=2 4/5.hasil berikut yg bnar adalah

Answer 1

M x n
= 1 3/7 x 120%
= 10/7 x 120/100
= 1.200/700
= 12/7

m x p
= 1 3/7 x 2 4/5
= 10/7 x 14/5
= 140/35
= 4

m : p
= 1 3/7 ÷ 2 4/5
= 10/7 ÷ 14/5
= 10/7 x 5/14
= 50/98
= 25/49

n : p
= 120% ÷ 2 4/5
= 120/100 ÷ 14/5
= 120/100 x 5/14
= 600/1.400
= 3/7

Jadi,hasil berikut yg benar adalah d. n : p = 3/7
