We can simplify second fratction by divide 2
4/2=2
6/2=3
2/(3xy^3)
common denomenator
factor
3x^2y=3*x*x*y
3xy^2=3*x*y*y
LCD=3*x*x*y*y=3x^3y^2
multiply first fraction by y/y and second fraction by x/x
(5y)/(3x^2y^2)-(2x)/(3x^2y^2)=
(5y-2x)/(3x^2y^2)
Answer:
![3m =\frac{57}{5}=11.4=11\ \frac{2}{5}](https://tex.z-dn.net/?f=3m%20%3D%5Cfrac%7B57%7D%7B5%7D%3D11.4%3D11%5C%20%5Cfrac%7B2%7D%7B5%7D)
Step-by-step explanation:
We know that
![m = 3\ \frac{4}{5}](https://tex.z-dn.net/?f=m%20%3D%203%5C%20%5Cfrac%7B4%7D%7B5%7D)
Therefore
![m = 3+\frac{4}{5}\\\\m=\frac{19}{5}](https://tex.z-dn.net/?f=m%20%3D%203%2B%5Cfrac%7B4%7D%7B5%7D%5C%5C%5C%5Cm%3D%5Cfrac%7B19%7D%7B5%7D)
Now multiply the value of m by 3.
![m=\frac{19}{5}\\\\3m=3*\frac{19}{5}\\\\3m =\frac{57}{5}=11.4](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B19%7D%7B5%7D%5C%5C%5C%5C3m%3D3%2A%5Cfrac%7B19%7D%7B5%7D%5C%5C%5C%5C3m%20%3D%5Cfrac%7B57%7D%7B5%7D%3D11.4)
The answer is 3m = 11.4
