29+m/5+m=19/7
Multiply both sides by 7 (5 + m)
203+7m=95+19m
12m=108
m=9



The fraction is 295. After adding m to numerator and denominator, the ratio of numerator to denominator is 19:7. What is m?


29 + M5 + M = 197, & nbsp; 19 × (5 + m) = 7 × (29 + m), & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 95 + 19m = 203 + 7m, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 12m = 108, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; m = 9



The fraction is five out of twenty-nine. After the numerator and denominator are added with m, the ratio of numerator and denominator is 19:7. What is m?

The fraction is 295. After adding m to numerator and denominator, the ratio of numerator to denominator is 19:7. What is m?


29 + M5 + M = 197, & nbsp; 19 × (5 + m) = 7 × (29 + m), & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 95 + 19m = 203 + 7m, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 12m = 108, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; m = 9
