Question

Сократить дроби.

 

2а-2с

____   = 

    8а

 

 

 

3х+3у

____   =

   3х-3у

Answer 1

(2a-2c)/8a=2(a-c)/8a=(a-c)/4a

(3x+3y)/(3x-3y)= 3(x+y)/3(x-y)=(x+y)/(x-y)

Answer 2

$\frac{2a-2c}{8a} = \frac{2(a-c)}{8a}= \frac{a-c}{4a}$
$\frac{3x+3y}{3x-3y} = \frac{3(x+y)}{3(x-y)}= \frac{x+y}{x-y}$
