Question

Вычислите: -0,25-3 1/2 2)-9 1/4-0,75 3)-3-2 3/5 4)-27-5 9/20 5)-16 8/25-7,3 6)-5,8-17 3/4.

Answer 1

-0,25-3 1/2= -25/100-3 50/100= -3 75/100= -3 15/20= -3 3/4
-9 1/4-0,75= -9 25/100-75/100= -9 100/100= -10
-3-2 3/5= -2 5/5-2 3/5= -4 8/5= -5 3/5
-27-5 9/20= -32 9/20
-16 8/25-7,3= -16 32/100-7 30/100= -23 62/100= -23 31/50
-5,8-17 3/4= -5 80/100-17 75/100= -22 155/100= -22 31/20= -23 11/20
