<h3><u>Write 3 fractions, using 10 as the denominator, who's sum is 1</u></h3>

<em><u>Solution:</u></em>
Given that,
We have to write 3 fractions, using 10 as the denominator, who's sum is 1
We know that, fraction is written as:

We have to write 3 fractions with 10 as denominator

Add these to check if its sum is 1

When denominators are same, we can add the numerators

Thus the three fractions are:

Let number of adult tickets be a , therefore number of student ticket be a+4 .
And total cost of the tickets is 58, that is

Distributing 2.50 on a+4
