This is a simple one just multiply the sides by the same number
14/32, 28/48
Convert the mixed numbers to the improper fractions:
![2\dfrac{3}{4}=\dfrac{2\cdot4+3}{4}=\dfrac{11}{4}\\\\19\dfrac{1}{4}=\dfrac{19\cdot4+1}{4}=\dfrac{77}{4}](https://tex.z-dn.net/?f=2%5Cdfrac%7B3%7D%7B4%7D%3D%5Cdfrac%7B2%5Ccdot4%2B3%7D%7B4%7D%3D%5Cdfrac%7B11%7D%7B4%7D%5C%5C%5C%5C19%5Cdfrac%7B1%7D%7B4%7D%3D%5Cdfrac%7B19%5Ccdot4%2B1%7D%7B4%7D%3D%5Cdfrac%7B77%7D%7B4%7D)
