i mean what is 0.54 divided by 0.756

Answer 1

Yes, it's 0.7142857143 which is 5/7.

Answer 2

Since for some reason you don't believe me, here's the long-winded version:
\[\Large \begin{array}{l}
\frac{{0.54}}{{0.756}} = 0.7142857143\\\\
0.54 = \frac{{27}}{{50}}\\
0.756 = \frac{{189}}{{250}}\\\\
\frac{{27}}{{50}} \div \frac{{189}}{{250}} = \frac{{27 \times 250}}{{50 \times 189}} = \frac{{6750}}{{9450}}\\\\
\frac{{6750}}{5} = \frac{{9450}}{7}\\\\
\frac{{6750}}{{9450}} = \frac{5}{7}
\end{array}\]

Answer 3

\[\frac{54}{100}/\frac{756}{1000}=\frac{5}{7} \]
