Answer 1

1)1/37-1/52=52-37/1924=15/1924

2)1/25-1/30=6-5/150=1/150

3)1/112-1/64=4-7/448=-3/448

Answer 2

$1) \frac{1}{37} - \frac{1}{52} = \frac{52 - 37}{1924} = \frac{15}{1924} \\ 2) \frac{1}{25} - \frac{1}{30} = \frac{6 - 5}{150} = \frac{1}{150} \\ 3) \frac{1}{112} - \frac{1}{64} = \frac{4 - 7}{448} = \frac{ - 3}{448} = - \frac{3}{448}$
