Question

СРОЧНО!!
$(frac{7}{12} - frac{1}{3}) * frac{16}{19}$

$(7frac{3}{5} - 2frac{4}{15}) * frac{9}{32}$

$( frac{11}{24} + frac{1}{6} )* 1frac{3}{5}$

$(7- 2frac{5}{16}) * frac{4}{25}$

Answer 1

=(7/12 - 4/12) * 16/19 = 3/12 * 16/19 = 1/4 * 16/19 = 4/19
-----------------------------------------------------------------

=(7 9/15 - 2 4/15) * 9/32 = 5 1/3 * 9/32 = 16/3 * 9/32 = 3/2 = 1 1/2
-------------------------------------

=(11/24 +4/24) * 1 3/5 = 15/24 * 8/5 = 3/3 = 1
------------------------------

=(6 16/16 - 2 5/16 ) *4/25 = 4 11/16 * 4/25 = 75/16 * 4/25 = 3/4
