a=2 1/3+3 1/6-2*1 1/4

b=2 4/5+4,9:24,5

c=9,8:98*(1:001)

d=5,4:6+(0,42:4,2)

e=(4,2:2,1)*(-274,23+277,23)

x=5,928:0,19-1 1/5 z=5 37/55:0,4*(2 3/4:3,25)

y=0,063:0,001*(11,2-1 1/5

Answer 1

a=2 1/3+3 1/6-2*1 1/4 = 2 2/6 + 3 1/6- 2 * 5/4 = 5 3/6 - 5/2 = 5 1/2 - 2 1/2 = 3

b=2 4/5+4,9:24,5 = 2 4/5 + 0,2 = 2,8 + 0,2 = 3

c=9,8:98*(1:001)= 9,8 : 98 * 100 = 0,1 * 100 = 10

d=5,4:6+(0,42:4,2)= 0,9 + 0,1 = 1

e=(4,2:2,1)*(-274,23+277,23)= 2 * 3 = 6

x=5,928:0,19-1 1/5= 31,2 - 1,2 = 30

z=5 37/55:0,4*(2 3/4:3,25) = 312/55 : 2/5 * (11/4 : 325/100) = 312/55 * 5/2 * (11/4 * 100/325) = 156/11 * 11/13 = 156/13 = 12

y=0,063:0,001*(11,2-1 1/5 = 63 * (11,2 - 1,2) = 63 * 10 = 630
