срочноооооооо помогите пж

Answer 1

1 -6 3/4 * 5 1/3 - 4 1/3 * 3 3/13 = -50

1. -6 3/4 * 5 1/3 = -27/4 * 16/3 = -36
2. 4 1/3 * 3 3/13 = 13/3 * 42/13 = 14
3. -36 - 14 = -50

2 (-2 1/ + 1/4) * (-2 2/11)= 42/11

1. -2 1/6 + 1/4 = -12/6 + 1/4 = -21/12= -7\4
2. -7\4 * (-2 2/11) = -7/4 * (-24/11 )= 42/11
