Convert Mixed Number: Simplifying 2 3/300 to Decimal Form

Q: Should I simplify the fraction before converting to decimal?

Yes! Always simplify first. $ \frac{3}{300} $ simplifies to $ \frac{1}{100} $, which is much easier to convert: 1 ÷ 100 = 0.01.

Q: How do I know when a fraction can be simplified?

Look for common factors in the numerator and denominator. Here, both 3 and 300 are divisible by 3, so $ \frac{3}{300} = \frac{1}{100} $.

Q: Can I use a calculator for the division?

Absolutely! But simplifying first makes it easier. Calculating 1 ÷ 100 is simpler than 3 ÷ 300, and both give you 0.01.

Q: How do I add the whole number part?

Simply add the whole number to your decimal: 2 + 0.01 = 2.01. The whole number stays in the ones place, and the decimal continues after the decimal point.
