Question

Выполните действия: 1)5/9*(- 3 6/7)-(-3 5/7)*3/52 2) (-2 1/3-3 1/4)*(2 3/4-0,59)

Answer 1

5/9*(- 3 6/7)-(-3 5/7)*3/52
1) 5/9*(-3 6/7)= 5/9*(-27/7)= -15/7= -2 1/7
2) -3 5/7*3/52= -26/7*3/52= -3/14
3) -2 1/7-(-3/14)= -30/14+3/14= -27/14= -1 13/14



(-2 1/3-3 1/4)*(2 3/4-0,59)
1) -2 1/3-3 1/4= -2 4/12 -3 3/12= -5 7/12
2)2 3/4- 59/100= 2 75/100-59/100= 2 16/100= 2 4/25
3)-5 7/12*2 4/25= -67/12*54/25= -1206/100= 12 6/100= -12 3/50
