Lars bought 5 boxes of pretzels. Each box has 8 ounces of pretzels. Before the party, her mom ate 6 ounces of pretzels. If one serving of pretzels is 2/3 ounce, how many servings will be left for the party?
(8*5-6) / 2/3 = 34 * 3/2 = ___
Started with 5 * 8 = 40 oz
mom ate 6 so have 40 - 6 = 34 oz
34 oz * 1 serving / (2/3 oz ) = 34*3/2 = 17*3 servings
Mom ate 9 servings??? , check bathroom scale !!!!
To find out how many servings of pretzels will be left for the party, we need to subtract the total amount of pretzels eaten by Lars's mom from the total amount of pretzels Lars bought. Then, we divide the remaining amount by the size of each serving.
First, let's calculate the total amount of pretzels Lars bought:
Since Lars bought 5 boxes of pretzels and each box has 8 ounces, we multiply these two numbers together:
5 boxes * 8 ounces/box = 40 ounces of pretzels
Next, let's calculate the total amount of pretzels Lars has after her mom ate 6 ounces:
40 ounces - 6 ounces = 34 ounces of pretzels
Finally, let's calculate the number of servings by dividing the remaining amount by the size of each serving:
34 ounces ÷ (2/3 ounce/serving) = 34 ÷ (2/3) servings
To divide by a fraction, we multiply by its reciprocal:
34 ÷ (2/3) = 34 * (3/2) = 51 servings
Therefore, there will be 51 servings of pretzels left for the party.
