FAQ

Everything you need to know about this question

Why can't I just compare 16 and 1.6 directly?

+

Because 1610 \frac{16}{10} means 16 divided by 10, not just the number 16. You must perform the division first to get the actual value for comparison.

Is there a faster way than converting to decimals?

+

Yes! You can convert the decimal to a fraction instead: 1.6 = 1610 \frac{16}{10} . Either method works, but converting fractions to decimals is usually easier.

What if I get a long decimal when dividing?

+

That's fine! Some fractions create repeating decimals or long decimals. Just calculate enough decimal places to make an accurate comparison.

How do I know when two numbers are equal?

+

Two numbers are equal when they have exactly the same value. After converting 1610 \frac{16}{10} to 1.6, both sides show 1.6, so they're equal.

Can I use this method for any fraction and decimal?

+

Absolutely! Converting fractions to decimals by dividing works for any fraction. This is a reliable method for all fraction-decimal comparisons.
