(4 целых 7/12 - 5 целых 3/4) : (7/36 - 1 целая 1/6) ; ! заранее

Answer 1

$(4 \frac{7}{12} - 5 \frac{3}{4} ) \div ( \frac{7}{36} - 1\frac{1}{6} ) = 1.5\\ 1)4 \frac{7}{12} - 5 \frac{3}{4} = 4 \frac{7}{12} - 5 \frac{9}{12} = - 1 \frac{1}{6} \\ 2)\frac{7}{36} - 1\frac{1}{6} = \frac{7}{36} - 1 \frac{6}{36} = - \frac{28}{36} \\ 3) - 1 \frac{1}{6} \div ( - \frac{28}{36} )= \frac{7 \times 36}{6 \times 28} = \frac{6}{4} = \frac{3}{2} = 1.5$
