Question 1:
To find how much more the large cookie weighs than the small cookie, we need to subtract their weights:
56 oz - 49 oz = 7 oz
So the answer is option D: 7/1 or 7 ounce.
Question 2:
Jenna buys one large cookie (56 oz) and two small cookies (49 oz each):
56 oz + 49 oz + 49 oz = 154 oz
So the answer is option C: 154/1 or 154 ounce.

D 435
To find how much more salt was used than pepper, we need to subtract the amount of pepper used from the amount of salt used:
57/1 - 35/1 = 22/1 or 22
So the answer is option B: 22/1 or 22.
Which statement about 56
– 34
is true?
Responses
A The least common denominator is 6.The least common denominator is 6.
B The difference is a whole number.The difference is a whole number.
C The least common denominator is 12.The least common denominator is 12.
D The difference is a mixed number.
The difference between 56 and 34 is:
56 - 34 = 22
Since 22 is a whole number, the answer is option B: "The difference is a whole number."

Last weekend Jane studied 4 23
hours for her history final and 4 14
hours for her math exam. How many hours in all did Jane study for the two tests?

hours8 3 4 hours
B 81112
hours8 11 12 hours
C 91112
hours9 11 12 hours
D 837
hours
To find the total number of hours Jane studied, we need to add the hours she spent studying for history and math:
4 23/1 + 4 14/1 = 8 37/1
To simplify, we can rewrite this as:
8 37/1 = 8 12/4 = 8 3/4
So the answer is D: 8 3/4 or 8.75 hours.

To find the total distance walked, we need to add the distances for Friday and Saturday:
23/1 + 12/1 = 35/1 or 35
So the answer is B: 35 miles.

913 - 314 = 599
We can rewrite this as a mixed number by dividing the numerator (599) by the denominator (13):
599 ÷ 13 = 46 with a remainder of 11
So the answer is option D: 46 11/13 or 5 11/13.

To find the fraction of students in the band who play either the flute or the clarinet, we need to add the number of students who play each instrument and then divide by the total number of students:
29/1 + 14/1 = 43/1
So out of every 43 students in the band, 29 play the flute and 14 play the clarinet. To find the fraction that play either instrument, we divide the total number who play by the total number in the band:
43/1 = 43/43
So the answer is A: 43/43 or 1 (which is equivalent to 7/8).

We need to find the least common denominator of 16 and 29, which is simply their product (16 x 29 = 464).
Then we convert each fraction to an equivalent fraction with the denominator of 464:
16/1 x 29/29 = 464/29
29/1 x 16/16 = 464/16
Now we can add these fractions:
464/29 + 464/16
To add these fractions, we need to find a common denominator, which is simply their product (29 x 16 = 464).
464/29 x 16/16 = 7424/464
464/16 x 29/29 = 13256/464
Now we can add:
7424/464 + 13256/464 = 20680/464
To simplify, we can divide both the numerator and denominator by their greatest common factor (which is 8):
20680/464 = 2585/58
So the answer is option C: 2585/58 or 5 12/58.
