What is frac{15}{4}b + \frac{5}{6} b" alt="-\frac{15}{4}b + \frac{5}{6} b" align="absmiddle" class="latex-formula">

Answer 1

Answer:

Step-by-step explanation:

First, let's get common denominators for both fractions -- in this case, the least common multiple of $4$ and $6$ is $12$.

$-\frac{15}{4}b + \frac{5}{6}b$

$-\frac{45}{12}b + \frac{10}{12}b$

Combining the terms together by adding the numerators will give us the answer:

$\frac{-45 + 10}{12}b$

$-\frac{35}{12}b$
