Question

$2 \frac{1}{4} \div (6 - 3 \frac{3}{8} \times 1 \frac{1}{3} )$
​

Answer 1

1) $3\frac{3}{8} *1 \frac{1}{3} = \frac{27}{8} *\frac{4}{3} = \frac{9*3*4}{4*3*2} = \frac{9}{2} = 4,5$

2) 6 - 4,5 = 1,5 = $\frac{3}{2}$

3) $2\frac{1}{4} : \frac{3}{2} = \frac{9}{4} *\frac{2}{3} = \frac{3*3*2}{2*2*3} = \frac{3}{2} = 1,5$

Ответ: 1,5
