Answer:
13
Step-by-step explanation:
To solve this, lets first find the number of footballs he still needs:
75-24 = 51
Now to find the number of packages, divide by 4, since there are 4 balls per package:
51/4 = 12 Remainder 3
Since there is a remainder, and the Coach MUST have at least 75, then we need to add a package to include the remainder:
12 + 1 = 13 Packages
Convert the fractions so they both have the same denominator (bottom part of the fraction)
1/5 = 7/35
This is because 5*7=35, so 1*7=7
1/7 = 5/35
This is because 7*5=35, so 1*5 =5
Then subtract the top numbers to get the answer:
Are you solving for x? If so x=7
If the troops hike 7km/2hr (read 7 kilometers per 2 hours), then to find how far they'd hike 4hr, just find multiply the top and bottom by 2. We do this because we found that to get from 2 to 4, we multiply by 2. And since this is a rate, we multiply the top by this value as well, so 7x2=14km
