Answer 1

Ответ:

-1305. 5/6

Пошаговое объяснение:

1) 8/51 * 15,3 = 8/51 * 153/10 = 4/1 * 3/5 = 12/5 = 2. 2/5

2) 2. 8/51 - 2. 2/5 = 2. 40/255 - 2. 102/255 = -62/255

3) -62/255 : 16/51 = -62/255 * 51/16 = -31/5 * 1/8 = -31/40

4) -31/40 - 38,4 = -31/40 - 38. 4/10 = -31/40 - 38. 16/40 = -38. 47/40 = -39. 7/40

5) -39. 7/40 : 0,03 = -1567/40 : 3/100 = -1567/40 * 100/3 = -1567/2 * 5/3 = -7835/6 = -1305. 5/6

Пошаговое объяснение:

(2 8/51- 8/51 * 15,3) : 16/51- 38,4) : (0,03 ) = - 1305 5/6

1) 8/51 * 15,3 = 8/51 * 15 3/10 = 8/51 * 153/10 =  4/1 * 3/5 = 12/5 = 2 2/5

2) 2 8/51 - 2 2/5 = 2 40/255 - 2 102/255 = -62/255

3) -62/255 : 16/51 = -62/255 * 51/16 = -31/5 * 1/8 = -31/40

4) -31/40 - 38,4 = -31/40-38 4/10 = -31/40 - 38 16/40 = -38 47/40 = -39 7/40 = - 39,175

5) -39 ,175 : 0,03 = -1305 5/6
