Answer: 4
Work:
(This are fractions) X/15 + 1/5 = 7/15
X/15 = 7/15 - 1/5
X/15 = 7/15 - 3/15
X/15 = 4/15
X=4

Step-by-step explanation:
Answer:
10 are 3/4 hr
4 are 1/2 hr
2 are 1/4 hr
Step-by-step explanation: we took 3/4 and multiplied x 10/1 = 30/4
we multiplied 1/2 x 4/1 =4/2 and we multiplied 1/4 x 2/1= 2/4
I converted 4/2 x 2/2 to give it the same common denominator as the other fractions 4/2 x 2/2=8/4
So 8/4 +30/4+2/4 = 40/4 divide this by 16 ( total number of cars) But somehow I am not getting the answer of 5/8, 9/16, 3/4 or 1/2 that are to choose from for the answer. 40/4 = 10 and 10/16 is simplified by dividing by 2/2 = 5/8
Answer: Each book weighs 2.5 pounds.
Step-by-step explanation: 75 divided by 2.5 is 30. Or you could also get the answer by multiplying 30 and 2.5 which it would be 75. So, therefor, the answer is 2.5.
To find the weight of each textbook, we divide the total weight by the number of books. Therefore, each book weighs 2.5 lb.
If thirty copies of a textbook weigh a total of 75 lb, to find the weight of each individual book, we need divide the total weight by the number of books.
Here is a step-by-step explanation of the solution:
Therefore, each book weighs 2.5 lb.
