Answer 1

(1 1/3 * 0,27 - 3 1/3 * 0,15) - 1500 * (-0,1)³ = 1  9/25
1) 1 1/3 * 27/100 = 4/3*27/100= 9/25
2) 3 1/3 * 15/100 = 10/3 * 15/100 = 5/10 = 1/2
3) 9/25 - 1/2 = 18/50 - 25/50 = -7/50
4) 1500 * (-0,1)³ = 1500 * (-0,001) = -1,5
5) -7/50 - (-1,5) = -7/50 + 1  5/10 = -7/50 + 15/10 = -7/50 + 75/50 = 68/50 =
 = 1  18/50 = 1 9/25
