Write the equation that the phrase represents, then solve the equation. The difference of a number and 1 2/7 is 5 1/2 ( with exp
BaLLatris [955]

Answer:

n = 95/14, or 6 11/14

Let the number be n.  Then:

n - 1 2/7 = 5 1/2.

Multiplying each term by the LCD (which is 14), we get:

14n - 18 = 77

Then 14n = 95  

and so the desired result is n = 95/14, or 6 11/14
