tentukan hasil pengurangan pecahan berikut ! a.1 7/8 -5/12 b.5 7/12-2 1/6 sederhanakan bentuk bentuk pecahan berikut ! a.4/5 dikali 3/8 b.7 7/8 dikali 1 5/7

17/8-5/12=(35-25)/96=10/96=5/48

a. 1 7/8 -5/12 = 15/8 - 5/12 = [tex] \frac{45-10}{24} [/tex] = [tex] \frac{35}{24} [/tex] = 1[tex] \frac{11}{24} [/tex]
b.  5 7/12-2 1/6 = 67/12 - 13/6 = [tex] \frac{67-26}{12} [/tex] = [tex] \frac{41}{12} [/tex] = 3 [tex] \frac{5}{12} [/tex]

a) 4/5 X 3/8 = 12/40 = 3/10
b) 7 7/8 dikali 1 5/7 = 63/8 X 12/7 =9/8 X 12= 108/8= 27/2 = 13 [tex] \frac{1}{2} [/tex]
