[tex] 1. \: 4\times 3\frac{1 }{2} = 6[/tex]
[tex]2. \: 4 \times \frac{1}{3} = 1.33 \\ 5 \times \frac{3}{4 } = 3.75 \\ 1.33 + 3.75 = 5.05 [/tex]
[tex]3. \: 17 \frac{3}{5} = \frac{88}{5} \\ 12 \frac{1}{4} = \frac{49}{4} \\ \frac{49}{4} \times \frac{88}{5} = 215.6[/tex]
[tex]4. \: 1 \frac{1}{4} \times 4 = 5 \\ 5 \div 10 = 0.5 \: liter[/tex]
[tex]5. \: 45 \times (5 \div 9) = 25[/tex]
