The correct answer is 2 5/18
The first step is to find a common denominator. (I will be using • to represent multiplication) The lowest common denominator that 3, 6, and 9 share is 18.
3 • 6 = 18
6 • 3 = 18
9 • 2 = 18
To rewrite your numbers using 18 as a denominator, you must multiply the numerator and denominator by the same number.
Since 3 • 6 = 18, 7 2/3 will be rewritten as
7 12/18 (since 2 • 6 = 12) we don’t have to worry about the whole number (7), so leave it as it is.
3 1/6 can be rewritten as
3 3/18, since 6 • 3 = 18 and 3 • 6 = 18
Once again we leave the whole number alone
2 2/9 can be rewritten as
2 4/18, since 9 • 2 = 18 and 2 • 2 = 4
Now we simply subtract our whole numbers and our fractions. Let’s first subtract our whole numbers.
7 - 3 - 2 = 2
Now we can subtract our fractions. Remember that when we subtract fractions, the denominator stays the same. In other words, we only subtract the numerator and ignore the denominator.
12/18 - 3/18 - 4/18 = 5/18
Therefore youre solution is
2 5/18
