Answer:
9 times as many as 3 is 27.
Step-by-step explanation:
Hi there! I can help you! So, 7/24 is less than 1/2 a day, because 1/2 is equivalent to 12/24 and 7/24 is less than 12/24. To find out how much less it is, let’s do subtraction.
12/24 - 7/24 = 5/24. 7/24 is less than half a day by 5/24.

Call the number of hardcover and paperback books, h and p.
Thus
h + p = 8 and the value equation is
4h + 2p = 26
Now multiply the top one by four and subtract from the second one...we get
4h + 2p = 26
-(4h + 4p = 32)
----------------
-2p = -6
p = 3 so that
h = 5 x + y = 8, (1)
4x + 2y = 26, (2)
where x and y are the numbers of hardcover and softcover books respectively.
To solve, multiply the equation (1) by 2 (both sides) and then distract it from the equation (2). You will get
4x - 2x = 26 - 16, or
2x = 10, or x = 5 - the number of hardcover books purchased.
Then from the equation (1) you get y = 3.
Check. 4*x + 2*3 = 4*5 + 2*3 = 26. OK.
