1. Hitunglah hasil operasi pecahan berikut! a. (3/8+3/4) x ( 6/5:4/5) b. (7/10-1/5) : (3/10+2/5)

a. 3/8+3/4= 12/32+24/32= 36/32= 18/16= 9/8
6/5:4/5 = 6/5×5/4= 30/20= 3/2
•9/8×3/2= 27/16
b. 7/10-1/5 = 35/50-10/50= 25/50= 1/2
3/10+2/5 = 15/50+20/50= 35/50= 7/10
1/2:7/10= 1/2×10/7 = 10/14= 5/7
semoga membantu:)
