а) $$\frac{83}{5} = \frac{80 + 3}{5} = \frac{80}{5} + \frac{3}{5} = 16 + \frac{3}{5} = 16 \frac{3}{5}$$
б) $$\frac{98}{11} = \frac{88 + 10}{11} = \frac{88}{11} + \frac{10}{11} = 8 + \frac{10}{11} = 8 \frac{10}{11}$$
в) $$\frac{37}{37} = 1$$
г) $$\frac{503}{16} = \frac{496 + 7}{16} = \frac{496}{16} + \frac{7}{16} = 31 + \frac{7}{16} = 31 \frac{7}{16}$$
д) $$\frac{77}{11} = 7$$
Ответ: а) $$16 \frac{3}{5}$$, б) $$8 \frac{10}{11}$$, в) $$1$$, г) $$31 \frac{7}{16}$$, д) $$7$$
