A recipe requires 3 1/2 cups of milk. Sam put in 1 1/8 cups and emptied the container. How much more milk does she need to put in?
Please help ASAP!!! :(
3 1/2 - 1 1/8 = 3 4/8 - 1 1/8 = 2 3/8
2 3/8
To solve this problem, we need to find out how much more milk Sam needs to put in.
First, let's add the amount of milk Sam put in (1 1/8 cups) to the initial amount of milk required by the recipe (3 1/2 cups):
1 1/8 cups + 3 1/2 cups
To add these fractions, we need a common denominator. The least common denominator for 8 and 2 is 8.
Next, we convert both fractions to have a denominator of 8:
1 1/8 cups = 8/8 + 1/8 = 9/8 cups.
3 1/2 cups = 4/2 + 1/2 = 5/2 cups = (5/2) * (4/4) = 20/8 cups.
Now, we can add the fractions:
9/8 cups + 20/8 cups = (9 + 20) / 8 cups
This gives us 29/8 cups.
To determine how much more milk Sam needs to put in, we subtract the amount she already put in from the total required:
29/8 cups - 9/8 cups = (29 - 9) / 8 cups
This gives us 20/8 cups.
Simplifying the fraction, we have:
20/8 cups = (20/4) / (8/4) = 5/2 cups.
Therefore, Sam needs to put in 5/2 cups (or 2 1/2 cups) more milk to complete the recipe.
