Simplify the fraction
198/264
as much as possible

3/4.

Step-by-step explanation:

Find the prime factors:

198 =  2 * 99

99 = 3 * 3 * 11

So 198 = 2 * 3 * 3 * 11.

264 = 4 * 66 = 2 *2 * 66

66 = 2 * 3 * 11

So 264 = 2 * 2 * 2 * 3 * 11.

Now we find the Greatest common factor os the 2 numbers:

It is 2 * 3 * 11 = 66.

Therefore we can now simplify the fraction:

198/66 / 264/66

= 3/4.

4 times

Step-by-step explanation:

1 quart is equivalent to 32 fluid ounces.

If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:

Tanvi can make her volcano erupt 4 times  with 1 quart of vinegar.
