If 2/3 of a class has brown hair, and 1/5 of the students with brown hair have blue eyes, what portion of the class has brown hair with blue eyes?
2/3 * 1/5
Of the 18 students, 4/6 have brown hair. How many of the students have brown hair?
To find the portion of the class that has brown hair with blue eyes, we need to find the fraction of students with both brown hair and blue eyes.
Given that 2/3 of the class has brown hair, we can calculate the fraction of the class with brown hair as 2/3.
Next, we need to determine the portion of students with brown hair who have blue eyes. It is stated that 1/5 of the students with brown hair have blue eyes. Therefore, the fraction of students with brown hair and blue eyes is (1/5) * (2/3).
To calculate this, we multiply the two fractions together:
(1/5) * (2/3) = 2/15
Therefore, 2/15 of the class has brown hair with blue eyes.
To find the portion of the class that has brown hair with blue eyes, we first need to calculate the fraction of students who have brown hair and blue eyes.
Step 1: Calculate the fraction of students with brown hair
Given that 2/3 of the class has brown hair, we can represent it as a fraction: 2/3.
Step 2: Calculate the fraction of students with brown hair and blue eyes
Given that 1/5 of the students with brown hair have blue eyes, we can represent it as a fraction: 1/5.
Step 3: Calculate the product of the two fractions
To find the portion of the class that has both brown hair and blue eyes, we multiply the fractions from step 1 and step 2:
(2/3) * (1/5) = 2/15
Therefore, the portion of the class that has brown hair with blue eyes is 2/15.
