Question

Сократи дробь: 7b−77\8b−88 = .

Answer 1

7b-77/8=. -21/8b,а в конце просто прибавляем -88,и получается -21/8b-88,т.к. b-число незьзя отнять))))

Answer 2

$\frac{7b - 77}{8b - 88 } = \frac{7(b - 11)}{8(b - 11)} = \frac{7}{8}$

Answer 3

To simplify the fraction, we need to find the greatest common divisor (GCD) of the numerator and denominator and then divide both the numerator and denominator by that value.

The given fraction is:

$\frac{7b - 77}{8b - 88}$

First, let's factor out the common terms from the numerator and denominator:

$\frac{7(b - 11)}{8(b - 11)}$

Now, we can see that both the numerator and denominator have a common factor of $b - 11$. So, we can cancel it out:

$\frac{7\cancel{(b - 11)}}{8\cancel{(b - 11)}}$

Leaving us with the simplified fraction:

$\frac{7}{8}$
