Help asap Which explains how to find the quotient of the division below? -3 1/3 divided by 4/9

noname [10]

Answer:

$-7\frac{1}{2}$

Step-by-step explanation:

To find the quotient, convert the mixed number to an improper fraction first

$-3\frac{1}{3}=-\frac{3*3+1}{3}=-\frac{10}{3}$

Find the quotient now

$\frac{(-10/3)}{(4/9)}=-\frac{10*9}{4*3}\\ \\=-\frac{90}{12}$

Simplify

Divide by $6$ both numerator and denominator

$=-\frac{15}{2}=-7.5$

Convert to a mixed number

$-7.5=-(7+0.5)=-(7+\frac{1}{2})=-7 \frac{1}{2}$
