If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio.
Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication.
Finally, solve for x and if you had 100 balloons, you will have 40 yellow balloons.
The first one is A. And Sowy but meh don't know the second one...
15.50h = 2294
h= 148 hours
4w = 148
w= 37 hours each week
Write and solve an equation of ratios, as follows:
32 fl oz 60 min
----------- = ------------
x 135 min
Then 60x = (32)(135) = 4320, and x = 72 oz.
damron should drink 72 fl. oz. of water if he rides 135 min.
