Answer:

3 gallons.

Step-by-step explanation:

If you add three gallons of water to 1 gallon of antifreeze, then there are 4 gallons total. That means that 1/4 of the solution is antifreeze, and 1/4 is equal to 25%.

Snowcat [4.5K]

solution

Find the equivalent ratio for 64%. Write your answer in simplest form.​

For this case we can do the following:

64% = 64/100

And if we simplify we got:

64/100 = 32/50 = 16/25 = 0.64

For what values of y:is the value of the fraction 7−2y /6 greater than the value of the fraction 3y−7 /12 ?
Fynjy0 [20]
Let's start by plugging in 1 for y. You get 7-2/6, which is 5/6. The other equation is 3-7/12, which equals -1/3. Now let's try 10. You get 7-2(10)/6, which is -13/6. The other equation is 3(10)-7/12, which is 23/12, and is larger!

1 is a value of y that could work!

Hope this helps!! :)
