Find a number if: 3/7 of it is 2 1/14

n = 2 1/14

Step-by-step explanation:

You have the equation (3/7)n = 2 1/14 and need to find the value of n.

First rewrite 2 1/14 as the improper fraction 29/14:

(3/7)n = 29/14.  Here the LCD is 14, so multiply both sides of this equation by that:

14(3/7)n = 14(29/14) = 29.  Simplifying this further, we get 6n = 29, so that:

n = 29/14, or  n = 2 1/14
