15/2+45/2=
6/1+8/3=
5/1-40/3=
8/3-7/1=
2 9/1+5 9/4=
3 5/4-2 5/3=
4 6/5-2 12/5=

Answer 1

$\frac{15}{2} + \frac{45}{2} = 30$

$\frac{6}{1} + \frac{8}{3} = \frac{26}{3} = 8 \frac{2}{3}$

$\frac{5}{1} - \frac{40}{3} = - \frac{25}{3} = - 8 \frac{1}{3}$

$\frac{8}{3} - \frac{7}{1} = - \frac{13}{3} = - 4 \frac{1}{3}$

$2( \frac{9}{4} ) + 5( \frac{9}{4} ) = \frac{117}{4 } = 29 \frac{1}{4}$

$3( \frac{5}{4} ) - 2( \frac{5}{3} ) = \frac{5}{12}$

$4( \frac{6}{5} ) - 2( \frac{12}{5} ) = 0$
