Sederhanakan bentuk pecahan berikut a.(3 1/3:2 3/4)+2 1/3 b.2 3/4+3 4/2 c.4q/4q-3p/8p d.(2 1/5×1/4)+(1 1/3:3/2)

ituu..................

a. (3 1/3 : 2 3/4) + 2 1/3
= (10/3 : 11/4) + 7/3
= (10/3 x 4/11) + 7/3
= 40/33 + 7/3
= 40/33 + 77/33
= 117/33
= 3 18/33
= 3 6/11

b. 2 3/4 + 3 4/2
= (2+3) + 3/4 + 2
= 5 + 2 + 3/4
= 7 3/4

d. (2 1/5 x 1/4) + (1 1/3 : 3/2)
= (11/5 x 1/4) + (4/3 x 2/3)
= 11/20 + 8/9
= 99/180 + 160/180
= 259/180
= 1 179/180

maaf klo slh :( g bisa bantu yang c.
