Given the equation:
2 ¾ - ⅓
Perform the indicated operation.
Solution:
In order to perform the indicated operation easily, we must convert first the mixed number to whole numbers. To do so, we exclude for a while the whole number and focus on the fraction part. Conver the fraction to decimals by dividing the numerator with the denominator, and then add the quotient to the excluded whole number.
2 ¾
= ¾
= 0.75
= 2.75
⅓
= 0.3333 (repeating)
= 2.75 - 0.33333 (repeating)
= 2.41667 (repeating)
The answer is in a repeating decimal form, hence we can represent it either with a word repeating enclose with a parenthesis, a dash line or ellipsis. In our case we will use the word.
Final answer:
= 2.41667 (repeating)
