Question

решите уравнение и выполните проверку (а-3/4)+7/16=11/16​

Answer 1

Ответ:

$(a - \frac{3}{4} ) + \frac{7}{16} = \frac{11}{16} \\ a - \frac{3}{4} = \frac{11}{16} - \frac{7}{16} = \frac{11 - 7}{16} = \frac{4}{16} = \frac{1}{4} \\ a - \frac{3}{4} = \frac{1}{4} \\ a = \frac{1}{4} + \frac{3}{4} = \frac{1 + 3}{4} = \frac{4}{4} = 1 \\ a = 1 \\proverim \\ 1) \: 1 - \frac{3}{4} = \frac{4 - 3}{4} = \frac{1}{4} \\ 2) \: \frac{1}{4} + \frac{7}{16} = \frac{4 + 7}{16} = \frac{11}{16} \\ otvet \: pravilno$
