Question

show that 1.272727...=1.27 can be expressed in the p/q,where p and q Are integer and q not equal 0

Answer 1

Let x = 1.27272....

10x = 12.7272... -(1)

1000x = 1272.7272... -(2)

Subtract 1 from 2

990x = 1260

x = 1260/990

= 420/330

x = 42/33 = 14/11

Thus it can be expressed in the form p/q where p = 14and q = 11
