Question

Simplify the following rational function: x/y/w/z+a/b

Answer 1

Is this the expression:
\[\ \frac{x}{y} (\frac{w}{z}) + \ \frac{a}{b} \]

Answer 2

If it is then we multiply the two on the left side of the +.
\[\ \frac{wx}{yz} \ + \ \frac{a}{b} \]

Answer 3

Then we use cross multiplication to get the same denominator:
\[\ \frac{wxb}{byz} \ + \ \frac{ayz}{byz} \ = \ \frac{wxb+ayz}{byz} \]

Answer 4

You can't simplify further so this is the most simplified form.

Answer 5

the expression actually is x over y over w over z plus a over b

Answer 6

sorry for not making that more clear.

Answer 7

\[\ \frac{\frac{x}{y} }{\frac{w}{z}} = \ \frac{x}{y} \ \times\ \frac{z}{w} \ = \ \frac{zx}{yw} \]

Answer 8

so now you have :
\[\ \frac{zx}{yw} \ + \ \frac{a}{b} \ = \ \frac{zxb + ayw}{ywb} \]
