3 2/3 divided by 3 4/5 if you could can you give it to me now I'm in a hurry

soldier1979 [14.2K]

Answer:

3 2/3 divided by 3 4/5 is $\frac{55}{57}$

Step-by-step explanation:

Operations With Fractions

Let's divide 3 2/3 by 3 4/5. Both fractions are in mixed format, so we have to write them as an improper fraction:

$\displaystyle 3\frac{2}{3}=3+\frac{2}{3}=\frac{9+2}{3}=\frac{11}{3}$

$\displaystyle 3\frac{4}{5}=3+\frac{4}{5}=\frac{15+4}{5}=\frac{19}{5}$

We must divide $\frac{11}{3}$ by $\frac{19}{5}$

To make it simple, we just multiply the first fraction by the reciprocal of the second fraction:

$\displaystyle \frac{\frac{11}{3} }{ \frac{19}{5}}=\frac{11}{3} * \frac{5}{19}=\frac{55}{57}$

3 2/3 divided by 3 4/5 is $\frac{55}{57}$
