Question

1.4/6-K=2/4
2. N+3/4=9/20

tolong jawabannya dan cara terus sama pembuktian hasilnya

Answer 1

1.4/6-K=2/4

4/6-2/4=8/12-6/12=2/12:2/2=1/6

4/6-1/6=3/6:3/3=1/2x2/2=2/4

K=1/6

2.N+3/4=9//20

3/4-9/20=15/20-9/20=6/20:2/2=3/10
3/10+9/20=6/20+9/20=15/20:5/5=3/4

N=3/10

Answer 2

1. k = 4/6 - 2/4
k = 8 - 6 / 12
k = 2 / 12
k = 1/6

4/6-1/6 = 2/4                √

2. n = 9/20 - 3/4
n = 9-15 / 20
n= -4/20
n= -1/5

-1/5 + 3/4 = 9/20        √
