Question

(15 целых 1/5 -х)+2 целых 3/4=6целых 1/6

Answer 1

$(15 \frac{1}{5} - x) + 2 \frac{3}{4} = 6 \frac{1}{6} \\ \frac{76}{5} - x + \frac{11}{4} = \frac{37}{6} \\ x = \frac{76}{5} + \frac{11}{4} - \frac{37}{6} = \frac{912}{60} + \frac{165}{60} - \frac{370}{60} = \frac{707}{60} = 12 \frac{13}{60}$
