Question

Найдите значение суммы -5/12+3/8,7/15+(-2/5),-1/8+3,5,5,8+(-1/4),-3/5+2/2,5/16+(-2/3) помогитееее

Answer 1

-5/12 + 3/8 = -10/24 + 9/24 = -1/24

7/15 + (-2/5) = 7/15 - 6/15 = 1/15

-1/8 + 3,5 = -1/8 + 28/8 = 3(3/8)

5,8 + (-1/4) = 5,8 - 0,25 = 5,55

-3/5 + 2/2 = -6/10 + 10/10 = 4/10 = 0,4

5/16 + (-2/3) = 15/48 - 32/48 = -17/48
