To clear the fractions in the equation \(\frac{1}{3}x + \frac{1}{6}y = 4\), Rashonda should multiply the entire equation by the least common multiple (LCM) of the denominators. In this case, the denominators are 3 and 6.
The least common multiple of 3 and 6 is 6.
So, multiplying every term in the equation by 6 gives:
\[ 6 \left(\frac{1}{3}x\right) + 6 \left(\frac{1}{6}y\right) = 6 \cdot 4 \]
This simplifies to:
\[ 2x + y = 24 \]
Thus, Rashonda should multiply the entire equation by 6 to clear the fractions.
