Toby sells nachos at the baseball concession stand. each serving if nachos contains about 3 1/3 onces of chips. which is the best estimate of the number of servings of nachos Toby could make from a 51 5/8 once bag of chips?

Answers

(51 5/8 ) / (4/3)= 1239/32
or 38 and 23/32 so you could round up to 39 servings or down to 38 it probably tells you what you should do in the instructions.

Mathematically 23/32 is greater than .5 so you should round up, but then again logically you can have an imaginary portion of nachos.

Final answer:

To find the best estimate of the number of servings of nachos Toby could make from a 51 5/8 ounce bag of chips, divide the weight of the bag by the weight of each serving. Toby could make about 177 servings of nachos from the bag.

Explanation:

To find the best estimate of the number of servings of nachos Toby could make from a 51 5/8 ounce bag of chips, we need to divide the total weight of the bag by the weight of each serving. The weight of each serving is 3 1/3 ounces, which is the same as 10/3 ounces. We can divide 51 5/8 by 10/3 to find the number of servings.

Converting the mixed number to an improper fraction, 51 5/8 is equivalent to 413/8. When we divide 413/8 by 10/3, we can multiply the numerator and denominator of the first fraction by the reciprocal of the second fraction: 413/8 multiplied by 3/10. This gives us (413 x 3) / (8 x 10) = 1239/80.

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 7. Dividing 1239 by 7 gives us 177, and dividing 80 by 7 gives us 11. Therefore, Toby could make about 177 servings of nachos from the 51 5/8 ounce bag of chips.

What is bigger, 4,000,000 mm or 4km

Answers

4,000,000 mm is equal to 4 km

4,000,000 mm = 4 km

We need to have the same unit to compare.

We can change km to mm

1 km is 1,000,000 mm so,
4 km is 4,000,000 mm

4,000,000 mm = 4,000,000 mm
Both are equal
