To find this answer, it is quite simple. This is because you use to cross multiply rule in order to solve the problem so you multiply
and you get 600=75x. Then you solve the equation like normal. Same thing for the second equation 90*72 and 80*w you will get 6480=80w. And then solve the equation from there. I hope this helps :)))
A glass holds 1/4 liter of water so if you have 4 cups you will have 1 liter of water. If you need 5 liters than you just multiply the number of cups per liter by the number of liters
