Решите задачу:

$1) \frac{59 ^{2} -41 ^{2} }{59 ^{2} +2*59*41+41 ^{2} } = \frac{(59-41)(59+41)}{(59+41)(59+41)} = \\ \\ = \frac{59-41}{59+41} = \frac{2}{100} =0.02 \\ \\ 2) \frac{87^{2} -2*87*67+67 ^{2} }{87 ^{2} -67 ^{2} } = \frac{(87-67)(87-67)}{(87-67)(87+67)} = \\ \\ = \frac{87-67}{87+67} = \frac{20}{154} = \frac{20}{77}$

$3) \frac{49 ^{2}-2*49*24+24 ^{2} }{46 ^{2}+2*46*24 +24 ^{2} } = \frac{(49-24) ^{2} }{(46+24) ^{2} } =( \frac{25}{70} ) ^{2} = \\ \\ =( \frac{5}{14} )^{2} = \frac{25}{196}$
