Understanding the Fraction 3 3/8
Before diving into the conversion process, it's essential to understand what 3 3/8 represents. This is a mixed number, which consists of a whole number (3) and a fraction (3/8). To convert this mixed number to an improper fraction, you multiply the whole number by the denominator of the fraction, add the numerator, and then place this sum over the original denominator.
For 3 3/8, the calculation would be:
3 * 8 + 3 = 24 + 3 = 27
So, 3 3/8 as an improper fraction is 27/8.
Converting 3 3/8 to a Decimal
To convert 3 3/8 to a decimal, you need to divide the numerator by the denominator. In this case, you divide 27 by 8.
27 ÷ 8 = 3.375
Therefore, 3 3/8 as a decimal is 3.375.
