How can i find the value of N that makes each number sentence correct?3/4 + N = 19/20 Solution 3/4-3/4+N= 19/20 -3/4 N= 19/20- 15/20 (20 is the common denominator and 4 goes into 20 5 times, 5 times 3 is 15) N= 4/20 (19-15 is 4. The bottom stays the same) N=1/5 (4 goes into 20 5 times, and into itself once. Reduce the fraction to it\'s smallest value).
