1. 3/5 = n/35
Answer with Solution:
5 × n= 3 × 35
5 × n= 105
n= 105 ÷ 5
n= 21
2. 15/n = 4/12
4 × n= 15 × 12
4 × n= 180
n= 180 ÷ 4
n= 45
3. 18/36 = 6/n
18 × n= 36 × 6
18 × n= 216
n= 216 ÷ 18
n= 12
4. 12/n = 35/42
35 × n= 12 × 42
35 × n= 504
n= 504 ÷ 35
n= 14.4
5. 3/n = n/27
n × n= 3 × 27
n × n= 81
n= 81 ÷ n²
n= 81/n²
6. 150/n = 1/10
1 × n= 150 × 10
1 × n= 1500
n= 1500 ÷ 1
n= 1500
7. 60/90 = 180/n
60 × n= 180 × 90
60 × n= 16,200
n= 16,200 ÷ 60
n= 270
