To determine the number of pastries with a fruit filling, 40% of 30 types is calculated, resulting in 12 types of pastries with a fruit filling.
The student asked how many types of pastries with a fruit filling are available at Sweet Treats Bakery, given that they have 30 types of pastries in total and 40% of them have a fruit filling. To find the answer, we calculate 40% of 30.
Step 1: Convert the percentage to a decimal by dividing it by 100. Thus, 40% becomes 0.40.
Step 2: Multiply the total number of pastries by the decimal. So, 30 × 0.40 = 12.
Therefore, the bakery has 12types of pastries with a fruit filling.
