you ate 1/4 of a pizza. your sister ate 1/6 of the pizza. how much of the pizza is left?
1/4 + 1/6 = 3/12 + 2/12 = 5/12
12/12 - 5/12 = ?
2/3
To find out how much of the pizza is left, you need to subtract the portions you and your sister ate from the total amount of the pizza.
First, let's find the common denominator for 1/4 and 1/6, which is 12.
To convert 1/4 to twelfths:
1/4 = (1 * 3)/(4 * 3) = 3/12
To convert 1/6 to twelfths:
1/6 = (1 * 2)/(6 * 2) = 2/12
Now, let's subtract the portions you and your sister ate from the total amount:
Total portions eaten = 3/12 + 2/12 = 5/12
To determine how much of the pizza is left, subtract the total portions eaten from the whole pizza.
Whole pizza - Total portions eaten
= 1 - 5/12
= (12/12) - (5/12)
= 7/12
Therefore, there is 7/12 of the pizza left.
To find out how much of the pizza is left, you need to subtract the fractions that you and your sister ate from one whole pizza.
First, let's find a common denominator for the fractions. The least common denominator (LCD) of 4 and 6 is 12.
Now, let's convert the fractions to have a denominator of 12:
- You ate 1/4 of the pizza, which is equivalent to 3/12.
- Your sister ate 1/6 of the pizza, which is equivalent to 2/12.
Next, subtract the fractions to find how much of the pizza is left:
12/12 - 3/12 - 2/12 = 7/12
Therefore, 7/12 of the pizza is left.
