1. Hitung lah penjumlahan pecahan biasa difoto tersebutNt :Rapi, benar ( ba )​

a. 1/2 + 3/4 = 2/4 + 3/4 = 5/4

b. 1/9 + 2/3 = 1/9 + 6/9 = 7/9

c. 1/4 + 7/12 = 3/12 + 7/12 = 10/12

d. 3/4 + 3/6 = 3/12 + 6/12 = 9/12

e. 2/9 + 5/6 = 4/18 + 15/18

f. 3/8 + 7/12 = 9/24 + 14/24 = 23/24

g. 1/2 + 3/4 + 5/6 = 6/12 + 9/12 + 10/12 = 25/12

H. 3/5 + 2/3 + 5/6 = 18/30 + 20/30 + 25/30

= 63/30
