2/5 of the students of a class of 50 students like mangoes where as 1 /5 like apples and rest like Banana. Find The fraction of the total number of student like banana?
Answers
Answer:
Total fraction =5/5
Fraction of students who like mango=2/5
apples=1/5
Therefore, students who like banana=5/5-(2/5+1/5)
=5/5-3/5
=2/5
Answer is 2/5
Step-by-step explanation:
Method 1
Let the fraction of students those who like banana be x
we know that when we add all the fractions, we get 1
i.e 2/5 + 1/5 + x = 1
=》 2 + 1 + 5x ÷ 5 = 1
=》2 + 1 + 5x = 1 × 5
=》3 + 5x = 5
=》 5x = 5-3
=》 5x = 2
=》 x = 2/5
So 2/5 of 50 students likes banana
Method 2
Students who like Mangoes = 2/5 of 50
= 2/5 × 50
= 20 students
Students who like apples = 1/5 of 50
= 1/5 × 50
= 10 students
So, no. of students out of 50 who like banana is
= 50 - 20 - 10
= 20 students
Fraction of the total number of student who likes banana = 20/50
=2/5 Answer
