Question

2,01+5, 1/4
9,5-1, 1/7
5,4*3, 1/3
5,1/2:0, 11
(3/4+0, 9) :0, 3

Accepted Answer

1.

2,01 + 5(1/4) = 2,01 + 5,25 = 7,26.

2.
9,5 – 1(1/7) = 9(1/2) – 1(1/7) = 19/2 – 8/7 = 133/14 – 16/14 = 117/14 = 8(5/14).

3.
5,4 * 3(1/3) = 5(2/5) * 3(1/3) = (27/5) * (10/3) = 18.

4.
5(1/2)/0, 11 = 5,5 * 0,11 = 0,605.

5.
(3/4 + 0, 9)/0, 3 = (0,75 + 0,9)/0,3 = 1,65/0,3 = 0,55.
