[tex] - 2 \frac{1}{2} - ( - 5 \frac{3}{4} ) = - 2 \frac{1}{2} + 5 \frac{3}{4} [/tex]
[tex] = 5 \frac{3}{4} - 2 \frac{1}{2} = \frac{23}{4} - \frac{5}{2} [/tex]
[tex] = \frac{23}{4} - \frac{10}{4} = \frac{23 - 10}{4} = \frac{13}{4} [/tex]
[tex] = \frac{4 + 9}{4} = \frac{4}{4} + \frac{9}{4} = 1 + \frac{9}{4} = 1 \frac{9}{4} [/tex]
Answer:
[tex]1 \frac{9}{4} [/tex]
Ok done. Thank to me :>
