Perform the indicated operations below and simplify ((a+b)/4) + ((2a-b)/5).
ArbitrLikvidat [17]

Answer:

\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{13a}{20} +\frac{b}{20}

Step-by-step explanation:

We have:

\frac{(a+b)}{4} +\frac{(2a-b)}{5}

We can use <em>common denominator</em>.

Observation:

If you have, \frac{a}{b} +\frac{c}{d}=\frac{(a*d)+(c*b)}{b*d}

Then,

\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{5(a+b)+4(2a-b)}{4*5}

Using <em>distributive property</em>:

Observation:

c(a+b)=ca+cb

\frac{5(a+b)+4(2a-b)}{4*5}=\frac{5a+5b+8a-4b}{20}=\frac{(5a+8a)+(5b-4b)}{20}

Finally,

\frac{(5a+8a)+(5b-4b)}{20} =\frac{13a+b}{20}=\frac{13a}{20} +\frac{b}{20}

The answer then is:

\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{13a}{20} +\frac{b}{20}
