Equivalent fractions represent the same amount but the numbers are different.<br><br> True OR False
belka [17]
I believe this answer to be true. This can be said because 4/2 equals 2 as does 24/12. Both of those fractions equals 2 yet they are two completely different fractions. Please tell me if I was right lol.

You can take LCM and then can add to see what's the sum.

The sum result of given expressions is given by: \dfrac{5}{y+5}

<h2>Given that:</h2>
  • To find sum of  \dfrac{3y}{y^2 + 7y + 10} and  \dfrac{2}{y+2}

<h2>Finding LCM and summing:</h2>

You can take LCM and then can add to see whats the sum.

\begin{aligned}\dfrac{3y}{y^2 + 7y + 10} + \dfrac{2}{y+2} &= \dfrac{3y}{(y+2)(y+5)} + \dfrac{2}{y+2}\\&= \dfrac{3y + 2(y+5)}{(y+2)(y+5)}\\&= \dfrac{5y+10}{(y+2)(y+5)}\\&= \dfrac{5(y+2)}{(y+2)(y+5)}\\&= \dfrac{5}{y+5}\\\end{aligned}

Thus, the sum of given expressions is given by:

\dfrac{5}{y+5}
