2 4/9+1 1/6=n,nilai n adalah..... 85%-3/4 adalah....... 75%+0,14 adalah....... 83%×3/4 adalah......jawab pakai cara ya makasih

2 4/9 = 22/9
1 1/6 = 7/6
22/9 + 7/6 = (88+42)/36 = 130/36 = 65/18

85% = 85/100 = 17/20
17/20 - 3/4 = (17-15)/20 = 2/20 = 1/10

75% = 75/100 = 15/20
0,14 = 14/100 = 7/50
15/20 + 7/50 = (75-14)/100 = 61/100

83% = 83/100
83/100 x 3/4 = 249/400
