Answer 1

Answer:

As question 1 and 3 is cut hence I will answer question 2 and 4.

By proportional method:

3:8::63:x

Since, product of means=product of extremes

3x=8×63

x=63×8/3

x=21×8

x=168

Denominator=168

Therefore,Fraction=63/168

Question 4:

By proportional method:

5:8::105:x

Since, product of means=product of extremes

5x=105×8

x=105×8/5

x=168

Denominator=168

Fraction=105/168
