975. 1) \(\frac{5a-5b}{10a}\) ; 2) \(\frac{3x+3y}{6x}\) ; 3) \(\frac{4m-4n}{8a+8b}\) ; 4) \(\frac{6p+6q}{12x+12y}\)

Решение:

1. \(\frac{5a-5b}{10a} = \frac{5(a-b)}{10a} = \frac{a-b}{2a}\)

2. \(\frac{3x+3y}{6x} = \frac{3(x+y)}{6x} = \frac{x+y}{2x}\)

3. \(\frac{4m-4n}{8a+8b} = \frac{4(m-n)}{8(a+b)} = \frac{m-n}{2(a+b)}\)

4. \(\frac{6p+6q}{12x+12y} = \frac{6(p+q)}{12(x+y)} = \frac{p+q}{2(x+y)}\)

Ответ: 1) \(\frac{a-b}{2a}\); 2) \(\frac{x+y}{2x}\); 3) \(\frac{m-n}{2(a+b)}\); 4) \(\frac{p+q}{2(x+y)}\).
