The fifth and sixth grades at Oak Street School are having fair.There are 50 students total and 3/5 of the students are fifth grade students.How many fifth grade students are entered in science fair?

3/5 * 50 = ?

To find out how many fifth-grade students are entered in the science fair, we first need to determine the number of fifth-grade students.

We know that 3/5 of the total students are fifth-grade students.

To calculate the number of fifth-grade students, we can multiply the total number of students by the fraction representing the proportion of fifth-grade students.

First, let's find the number of fifth-grade students:

Number of fifth-grade students = Total number of students × Proportion of fifth-grade students

Number of fifth-grade students = 50 students × 3/5

To multiply fractions, we multiply the numerators (top numbers) together and the denominators (bottom numbers) together:

Number of fifth-grade students = (50 × 3) / 5

Number of fifth-grade students = 150 / 5

Number of fifth-grade students = 30

Therefore, there are 30 fifth-grade students entered in the science fair.
