To find the amount of French fries Sarah's mom ate, we need to subtract the amount of French fries Sarah ate from the total amount baked by Sarah's mom.
The total amount of French fries baked by Sarah's mom is 2 5/6 pounds.
Sarah ate 1 2/3 pounds of French fries.
To perform the subtraction, we need to subtract 1 2/3 pounds from 2 5/6 pounds.
To subtract fractions, we need to ensure that the denominators are the same. In this case, the denominators are 6 and 3. To make the denominators the same, we can convert the fraction 1 2/3 to an improper fraction.
1 2/3 = (3 * 1 + 2) / 3 = 5/3
Now that we have the fractions with the same denominator, we can subtract them:
2 5/6 - 1 2/3 = (2 * 6 + 5) / 6 - (1 * 3 + 2) / 3
= (12 + 5) / 6 - (3 + 2) / 3
= 17/6 - 5/3
To subtract these fractions, we need to find a common denominator. The common denominator of 6 and 3 is 6.
17/6 - 5/3 = (17/6) * (3/3) - (5/3) * (2/2)
= 51/18 - 10/6
Now that the denominators are the same, we can subtract the fractions:
51/18 - 10/6 = (51 - 10) / 18
= 41/18
So, Sarah's mom ate 41/18 pounds of French fries.
Therefore, the operation used to find the amount of French fries Sarah's mom ate is subtraction.
