Question

What fraction must be subtracted from the sum of 14 and 1/6 to have an average of 1/12 of all the
two fractions?
(1) 1/3
(2) 1/2
(3) 1/4
(4) 1/8​

Answer 1

Answer:

(3)1/4

Step-by-step explanation:

The question must be revised.

Instead of 14,there should be 1/4.

The method is:

Let the fraction be 'x'.

(1/4+1/6-x)/2=1/12

=>(3+2-12x)/12=1/6

=>(5-12x)/2=1

=>(5-12x)=2

=>(-12x)=2-5

=>(-12x)=(-3)

=>x=(-3)/(-12)

=>x=1/4
