Question

1. 1,25 - 0,5 × ¼ =
2. ¼ + 1,5 ÷ 0,25 =
3. 2 4/5 × ⅛ - 0,15 =
4. 35% × (0, 25 + 1/5) =
5. 3/5 ÷ (75% - ½) =​

Answer 1

[tex]1.25 - 0.5 \times \frac{1}{4} = \frac{9}{8} [/tex]

[tex] \frac{1}{4} + 1.5 \div 0.25 = \frac{25}{4} [/tex]

[tex]2 \frac{4}{5} \times \frac{1}{8} - 0.15 = \frac{1}{5} [/tex]

[tex]35\% \times (0.25 + \frac{1}{5} ) = \frac{21}{80} [/tex]

[tex] \frac{3}{5} \div (75\% - \frac{1}{2} ) = \frac{12}{5} [/tex]
