what is the average of these fractions? 1/12, 1/6, 1/4, 1/3, and 5/12 i need help asap due tomrrow
To find the average of a set of fractions, you need to add them up and then divide the sum by the total number of fractions.
Here's the step-by-step process to find the average of the given fractions:
Step 1: Add up the fractions:
1/12 + 1/6 + 1/4 + 1/3 + 5/12
To add fractions with different denominators, we need to make the denominators the same. In this case, we can use the least common denominator (LCD), which is 12.
So, let's convert each fraction to have a denominator of 12:
1/12 + 2/12 + 3/12 + 4/12 + 5/12
Step 2: Add the numerators together:
1 + 2 + 3 + 4 + 5 = 15
Step 3: Keep the denominator of 12 (since the denominators are the same now):
15/12
Step 4: Simplify the fraction if necessary:
In this case, the fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
15 ÷ 3 / 12 ÷ 3 = 5/4
Step 5: Divide the sum by the total number of fractions:
Since there are five fractions, divide 5/4 by 5:
5/4 ÷ 5 = 1/4
So, the average of the given fractions is 1/4.

Change all the denominators to 12ths.
For example, 1/6=2/12 (multiply numerator and denominator by 2)
Then you can add all the numerators to get the answer in twelfths.
Try it yourself.
