5 5/8 as a Decimal

5 5/8 as a decimal is 5.625. A mixed number like this is really two separate pieces - a whole number and a fraction - and only one of them needs converting.

How to Convert 5 5/8 to a Decimal

Split the mixed number into its two parts: the whole number 5, and the fraction 5/8. The whole number doesn't change at all - it's already a decimal. The fraction is what needs converting, as we cover in more depth in 5/8 as a Decimal: divide 5 by 8 to get 0.625. Then just place that after the whole number: 5 + 0.625 = 5.625.

Why This Works

A mixed number is shorthand for addition - 5 5/8 literally means 5 + 5/8. Since decimals and fractions can both represent parts of a whole, you can convert each part on its own and combine them, rather than needing a special process just for mixed numbers.

5 5/8 as a Percentage

Multiply the full decimal by 100: 5.625 × 100 = 562.5%. Percentages over 100% are normal once a number is bigger than one whole - it just means "more than the whole amount," which checks out since 5 5/8 is more than five wholes.

Converting Any Mixed Number

Keep the whole number untouched, convert only the fraction part, then add the two together. That's the entire method, whether the fraction is eighths, quarters, or anything else.
