I am stuck.

Mike's truck engine holds 1 1/4 gallons of oil in the engine now, how many more quarts of oil does Mike need to add to fill the engine to capacity?

Having trouble on do I subtract or?? what do I do?

To solve this problem, you need to understand the conversion between gallons and quarts. There are 4 quarts in 1 gallon.

First, convert the given amount of oil from gallons to quarts. In this case, Mike's truck engine holds 1 1/4 gallons of oil, so you can multiply 1 1/4 by 4 to find the equivalent in quarts.

1 1/4 gallons * 4 quarts/gallon = 5 quarts

Therefore, Mike's truck engine currently contains 5 quarts of oil.

To find out how many more quarts of oil Mike needs to add to fill the engine to capacity, you need to subtract the current amount of oil from the engine's capacity.

To do this, you'll first need to know the engine capacity in quarts. If you don't have that information, you cannot determine the exact number of quarts Mike needs to add.

If you do have the engine capacity in quarts, you can subtract the current amount of oil (5 quarts) from the capacity to find out the additional amount needed.

Some information is missing.

The engine has 1 1/4 gallons of oil in it now? And the question is how much more oil is needed to fill to capacity (full).

What is the capacity of oil in the engine?

Oh oops. if there are 3 quarts of oil in the engine now, how many more quarts...

1 gallon = 4 quarts

try it now.

13 quarts?

Needs two more quarts?? I feel this is right
