Justify why a/b x b/c x c/d x d/e is equal to a/e when b, c,d, and e are not zero

iVinArrow [24]

The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e

Further explanation:

We have to evaluate the expression

Given expression is:

$\frac{a}{b}*\frac{b}{c}*\frac{c}{d}*\frac{d}{e}$

We can also write the expression as:

$\frac{a.b.c.d}{b.c.d.e}\\$

The terms that are both in numerator and denominator will be cancelled out.

So the final expression will be:

$\frac{a}{e}$

The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e
