a)
[tex]x \div \frac{6}{10 } = \frac{33 - 3}{9 } = \frac{30}{9} = \frac{10}{3} \\ x = \frac{10}{3} \times \frac{6}{10} = \frac{60}{30} = \frac{2}{1} = 2[/tex]
b)
[tex]x \div \frac{25}{10} = \frac{26 - 2}{90} = \frac{24}{90} = \frac{12}{45} \\ x = \frac{12}{45} \times \frac{5}{2} \\ x = \frac{6}{8} = \frac{3}{4} [/tex]
7.
a)
[tex]x = \frac{5}{4} + \frac{1}{4} = \frac{6}{4} [/tex]
c)
[tex] \frac{1 \times 4 + 3}{4} + x = \frac{11}{4} \\ x = \frac{11}{4} - \frac{7}{4} = \frac{4}{4} = 1[/tex]
Sper că te-am ajutat !
