15)  sisi pendek =  9/4 x  3 =  6,75 cm

16)   6a  + b = 6(3) + 4 = 22
4a  +  5b =  4(3) + 5(4)=  32
22 : 32 = 11 ;  16

17.  drama =  7/12 x 72 =  42
misteri  =   5/12 x  72 =  30
banyak buku misteri  =  42 - 30 = 12

20.  p=  7 x 21 / 49
p =  21/7
p =  3

Jawaban:

9/4 × 3

(9 ÷ 4) × 3

6,75cm

6(3) + 4 = 22

4(3) + 5(4) = 32

22 : 32 = 11:16

7/12 × 72

(7 ÷ 12) × 72

42

5/2 × 72 = (5 ÷ 2) × 72 = 30

42 - 30 = 12

2a = 6

a = 6/2

a = 3

3 + b = - 1

b = - 2

(9 - 4) : (9 + 4)

5:13

2 : 80

2 : 8.000.000

2 ÷ 2 : 8.000.000 ÷ 2

1 : 4.000.000

7 × 21/9

21 ÷ 7
