can someone answer this in need
on this question

Step-by-step explanation:

Before adding the fractions we require them to have a common denominator.

multiply the numerator/denominator of the first faction by 2 and the numerator/denominator of the second fraction by 7, that is

- +

= - +

Now add the numerators leaving the denominator

= = = 2

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
