Answer 1

Answer:

1) 10

2) 81

3) 50

4) 6

5) 50

Step-by-step explanation:

1) 4:x = x:25

x^2 = 25×4 = 100

x =√100 = 10

2) 9× 63 = _×7

_ =9×63/7 = 9×9 = 81

3) 25% of 200 = 200/4 = 50

4) 4:3 = 8:x

4x = 3×8 = 24

x = 24/4 = 6

5) 5% of 100 = 10% of x

5 = 10% of x = (10/100)* x = x/10

5 = x/10

x = 50
