Question

Математика: ((1.2/3)²-5/3): 10,2/3-1/16 вычислить

bogussasa7 · Answer

((1 2/3)^2 - 5/3) : 10 2/3 - 1/16 = 1/24

1) (1 2/3)^2 = 5/3 * 5/3 = 25/9 = 2 7/9
2) 2 7/9 - 5/3 = 2 7/9 - 1 2/3 = 2 7/9 - 1 6/9 = 1 1/9
3) 1 1/9 : 10 2/3 = 10/9 : 32/3 = 10/9 * 3/32 = (5*1)/(3*16) = 5/48
4) 5/48 - 1/16 = 5/48 - 3/48 = 2/48 = 1/24
