To find the amount of french fries Sarah's mom ate, we need to subtract the amount Sarah ate from the total amount baked by her mom. Therefore, we would use the subtraction operation.
To find the amount of french fries Sarah's mom ate, we need to subtract the amount Sarah ate from the total amount that was baked.
The operation that we would use in this case is subtraction.
Here's how you would calculate the amount Sarah's mom ate:
Start with the total amount of french fries baked: 2 5/6 pounds.
Subtract the amount Sarah ate: 1 2/3 pounds.
To subtract mixed numbers, we need to convert them into improper fractions.
2 5/6 pounds can be written as 17/6 pounds.
1 2/3 pounds can be written as 5/3 pounds.
Now, subtract the fractions:
17/6 pounds - 5/3 pounds
To subtract fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 6 and 3 is 6.
Converting both fractions to have a denominator of 6:
(17/6) - (5/3)
Rewriting both fractions with a denominator of 6:
(17/6) - (10/6)
Now, we can subtract the fractions:
(17 - 10)/6 = 7/6
So Sarah's mom ate 7/6 pounds of french fries.
