To convert a mixed fraction into a percent, first, we convert the given fraction into a decimal number, and then we multiply the decimal number by 100.
Notice that:
[tex]5\frac{1}{4}=5+\frac{1}{4}=5+0.25=5.25.[/tex]Therefore, 5 1/4 as a decimal number is 5.25.
Now, multiplying 5.25 by 100 we get:
[tex]5.25\times100=525.[/tex]Therefore, 5 1/4 as a percent is 525%.
Answer: 525%.
