The ratio of red marbles to blue marbles in a bag is 3: 4 . what is a possible total number of marbles?

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.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
