Question

Сократите дробь:
25×17×44
______________
51×17×75


8×3+8×23
____________
3×16


17×48
________
17×16-9×16



14×5-14×3
______________
21×9+21×3

Answer 1

25*17*44/51*8*75= 25*44 / 3*8*75= 44/ 3*8*3= 11/ 3*2*3= 11/18

(8*3+8*23)/3*16= 8*(3+23) /3*16 = 26/ 3*2= 13/3

17*48/(17*16-9*16)= 17*48/ 16*(17-9)= 17*3/ 8= 51/8

(14*5-14*3)/(21*9+21*3)= 14*(5-3) / 21*(9+3)= 2*2 /3*12= 1/ 3*3= 1/9
