To find the total amount of liquid that Bernard used, we need to add the amount of oil and the amount of water.
Bernard used 2 cups of oil and 1 3/4 cups of water.
To add these two amounts, we need to find a common denominator for the fractions.
The denominator of 1 3/4 is 4, so we need to express 2 cups as a fraction with a denominator of 4.
2 cups is equal to 8/4 cups.
Adding 8/4 cups of oil and 1 3/4 cups of water, we get:
8/4 cups + 1 3/4 cups = 8/4 cups + 7/4 cups = 15/4 cups.
Therefore, Bernard used a total of 15/4 cups of liquid.
