Answer:

Step-by-step explanation:
Make the denominators of the fractions the same and combine them
Then simplify the fraction
Then subtract how many gallons you have from how many you want
You will need 2.5 gallons to make 3 gallons
Question 1:
First, let's convert both mixed numbers to an improper fraction with a denominator of 8.
4 1/2= 32/8+4/8=36/8
1 7/8= 8/8+7/8= 15/8
Now since the number below the line in the fractions are the same, we can compare them.
Total grapes= 4 1/2 pounds or 36/8 pounds
Red grapes=1 7/8 pounds or 15/8 pounds
Green grapes= ?
To solve for the green grapes, we need to subtract the number of red grapes from the number of total grapes.
36/8=15/8=21/8
Green grapes= 21/8
since 21/8 is an improper fraction, lets convert it to a mixed number
21/8= 2 5/8
Answer: B 2 5/8
Question 2: 5.927 to 5.93
This number was rounded to the nearest hundredths place. We see the number two, was the number being rounded/changed in the action taken. Since the number 2 is in the hundreds place, the answer is C
Answer=C
