Александра Матвеева · Answer 1

A) 4/9 : 3/8 = 4/9 * 8/3 = (4 * 8) / (9 * 3) = 32/27;

b) 3/7 : 9/14 = 3/7 * 14/9 = (3 * 14) / (7 * 9) = (3 * 2 * 7) / (7 * 3 * 3) = 2/3;

c) 86/113 : 43/1 = 86/113 * 1/43 = (2 * 43) / (113 * 43) = 2/113;

d) 27/64 : 9 = 27 / (64 * 9) = (3 * 9) / (64 * 9) = 3/64;

I) 8 : 2/3 = (8 * 3) / 2 = 4 * 3 = 12;

f) 7 : 3 = 7/3.
