3/4
1) 5
[tex] \frac{5}{2} \times \frac{1}{2} = \frac{5}{4} [/tex]
2)
[tex] \frac{10}{3} + \frac{5}{4} = \frac{40}{12} + \frac{15}{12} = \frac{55}{12} [/tex]
[tex] \frac{55}{12} \div \frac{5}{3} = \frac{55}{12} \times \frac{3}{5} = \frac{11}{4} [/tex]
[tex] \frac{11}{4} - \frac{7}{4 } = \frac{3}{4} [/tex]
