Hey there! :D
Divide 15 by the numerator so we can find 1/7.
15/5= 3
3*7= 21
The number is 21.
I hope this helps!

the answer is 0.2 or one fifths
The second and last one.
The second one multiplies the cost of each type of ticket by two, therefore saying that you wanted to buy two of each type of ticket.
The last one multiplies the cost of a single ticket of all three types and multiplies it by 2.
20x4=80
i am assuming this is correct this is how i learned just take all numbers in equation and multiply by each other
