Question

In a class of 40 students 2/5 of the total number of students went for a picnic. How many students went to picnic

Answer 1

Answer:

If 2/5 are boys then 3/5 are girls

These added together equal 5/5 which is the total number in the class ( 45 in this example )

45 divided by 5 equals 9

3 fifths would be 3 x 9 = 27 girls

The other way is to let x = number of girls

multiply 45 ( total # students) by (3/5)

x = 45 (3/5)

x = 135/5 = 27 girls

Answer 2

Answer:

• 16 students.

Explanation:

Given

• Total strength of the class = 40
• Part of students who went for a picnic = 2/5

To find

• How many students went to the picnic.

Solution

⇾ Number of students who went for the picnic,

Part of students who went for the picnic × Total number of students

• 2/5 × 40
• 16

∴ 16 students went to the picnic.
