Answer 2

96*87+66/96*88-36

= 96 * 87 + 66 / 96 * 87 + 96 - 36

= 96 * 87 + 66 / 96 * 87 + ( 96 - 36 )

= 96 * 87 + 66 / 96 * 87 + 66

= 1

Answer 3

\(\frac{96\cdot87+66}{96\cdot88-36}\)

\(=\frac{16\cdot6\cdot87+6\cdot11}{16\cdot6\cdot88-6\cdot6}\)

\(=\frac{6\cdot\left(16\cdot87+11\right)}{6\cdot\left(16\cdot88-6\right)}\)

\(=\frac{1392+11}{1408-6}\)

\(=\frac{1403}{1402}\)
