Question

Diketahui : p = 5 2per 7
q = 1per 4
r = 3 1per 2
Nilai dari p-q:r.....
a. 3 3per14
b. 3 9per14
c. 5 3per14
d. 5 9per14

Answer 1

P = 5 2/7 = 37/7
q = 1/4
r = 3 1/2 = 7/2

p-q:r = 37/7 - 1/4 : 7/2
kerjakan operasi pembagian terlebih dahulu
= 37/7 - (1/4 : 7/2)
= 37/7 - (1/4 x 2/7)
= 37/7 - (1/14)
=37/7 - 1/14
samakan penyebutnya
= 74/14 - 1/14 = 73/14 = 5 3/14
