(100 5/8) / (14 3/8)
(805 / 8) / (115/8) =
805/8 * 8 / 115 =
805 / 115 =
7 <===
X-(x+5) I'm pretty sure that's it.
Answer:
<u>72 pounds of cat food will feed the cat for 192 days</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Amount of cat food the cat eats every day = 3/8 pound
2. For how many days 72 pounds of this cat food feed the cat ?
72 pounds = 576/8 pounds
Now we use this equivalent fraction to calculate the number of days, this way:
576/8 ÷ 3/8 = 576/8 * 8/3 (using the multiplicative inverse)
576/8 * 8/3 = 576/3 = 192
<u>72 pounds of cat food will feed the cat for 192 days</u>
