Ответ: 3 11/2=3+5 1/2=8 1/2. Тогда
4 1/3*|у¦+1 3/4=8 1/2 или 4 1/3*|у|=6,75 или |у|=27*3/(4*13)=1 29/52 или
у1=1 29/52, у2=-1 29/52.
Пошаговое объяснение:
360÷1/2=360÷2=180. 360×3÷4=270. 360×4÷5=288. 360×5÷6=300. 360×5÷8=225. 360×7÷10=252. 360×5÷12=150. 360×7÷20=126
1) 3/15 - 2 7/25 = 3/15 - 57/25 = 15/75 - 171/75 = -156/75
2) -156/75 : 27/25 = - 156/75 * 25/27 = - 52/27
<span>3) - 52/27 + 17/13 = -676/351 + 459/351 = 217/351
