Answer:
23-40
Step-by-step explanation:
First, you do 63 - 23, which would be 40. Since 23 to 40 is the simplest form of this ratio, no extra steps are needed. Order is important in ratios, so paperback to hardcover would be a ratio of 23 to 40, or 23-40.
23 and 40
660
V= l×w×h/3
V= 24×11×7.5/3
V=1 980÷3
V= 660
