Anna bakes 12 blueberry muffins, 20 bran muffins and 8 apple muffins. what % of muffins are blueberry. show all work
30% are blueberry muffin
12/(12 + 20 + 8) = ?
Multiply the decimal answer by 100 to get the percent.
To find the percentage of blueberry muffins, we need to calculate the ratio of the number of blueberry muffins to the total number of muffins, and then express it as a percentage.
Step 1: Calculate the total number of muffins.
12 blueberry muffins + 20 bran muffins + 8 apple muffins = 40 total muffins.
Step 2: Calculate the ratio of blueberry muffins to total muffins.
12 blueberry muffins ÷ 40 total muffins = 0.3
Step 3: Convert the ratio to a percentage.
0.3 × 100% = 30%
Therefore, 30% of the muffins are blueberry.
To find the percentage of muffins that are blueberry, follow these steps:
1. Calculate the total number of muffins:
blueberry muffins: 12
bran muffins: 20
apple muffins: 8
Total muffins = 12 + 20 + 8 = 40 muffins
2. Determine the number of blueberry muffins as a fraction of the total number of muffins:
Number of blueberry muffins / Total muffins = 12 / 40
Simplifying the fraction, we get:
12 / 40 = 3 / 10
3. Convert the fraction into a percentage:
Percentage = (fraction value) x 100
= (3 / 10) x 100
To simplify, divide the numerator by the denominator:
Percentage = (30 / 100) x 100
= 30%
Therefore, 30% of the muffins are blueberry.
