To find how much x represents of a y quantity as a percentage, we just find their ratio(x/y) and multiply by a hundred. Applying this to our situation, we just need to find the ratio between 19.2 and 20, and multiply by 100.
![\begin{gathered} (19.2)/(20)=0.96 \\ 0.96*100=96 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/9i7ymm8nnkkonh41f1u2ipoamvasbgaa0l.png)
19.2 is equal to 96% of 20.
