2 tickets cost $8.10. 1 ticket is $4.05. Just multiply the money he has by .6 for 2 tickets and then divide the number you get by 2 for the price of 1 ticket. Hope this helps!
(5/3)*(7/3) = 35*(1/3)²
The area is 35 square units.
So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:
5 to 10
We would change this into:

Because the problem says to simplify, we can divide both sides by 5 and simplify it into:

If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.
