Question

ktoś zrobi pleaseeeeee​

Answer 1

a)

[tex] \frac{1}{4} + 0.5 = \frac{1}{4} + \frac{1}{2} = \frac{1}{4} + \frac{2}{4} = \frac{3}{4} [/tex]

b)

[tex] \frac{12}{20} \times \frac{2}{3} = \frac{4}{10} \times 1 = \frac{4}{10} = 0.4[/tex]

c)

[tex]3.5 \div 0.2 = 3 \frac{5}{10} \div \frac{2}{10} = \frac{35}{10} \times \frac{10}{2} = 35 \times \frac{1}{2} = \frac{35}{2} = 17 \frac{1}{2} = 17.5[/tex]

d)

[tex]2.4 - 0.26 = 2 \frac{4}{10} - \frac{26}{100} = \frac{24}{10} - \frac{26}{100} = \frac{240}{100} - \frac{26}{100} = \frac{214}{100} = 2.14[/tex]
