Answer:
B I'm pretty sure..............
A proportion is a statement that two ratios are equal. A ratio is a comparison of two different quantities. "Miles per hour" is a ratio. "Dollars per pound" is a ratio. A proportion is that two of these things are equal.
For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:
That's a portion.
When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information. You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.
If your first ratio is "miles over hours," then the next ratio has to have the same organization.
If your first ratio is "rise over run," then the next ratio has to have the same organization.

Hello!
Ok so the summation of 1/4+1/2+3/4+5/8+3/10 = 97/40
we find this by finding the GCF of the set of numbers we have here. So we get 40 is the GCF. So we get:
10/40+20/40+30/40+25/40+12/40=97/40
Hope this helps! Any questions please just ask! Thank you so much!
Answer:
7500 revolutions
Step-by-step explanation:
1 rotation of his bicycle tires is equivalent to 1 circumference in linear distance.
circumference = π*diameter = π*20 = 62.8 in
If 1 foot is equivalent to 12 inches, then 62.8 in are equivalent to:
1 ft / x ft = 12 in / 62.8 in
x = 62.8/12 = 5.2 ft
If 5280 ft are equivalent to 1 mile, then 5.2 ft are equivalent to:
5280 ft / 5.2 ft = 1 mile / x mile
x = 5.2/5280 = 0.001 mile
So, when 1 revolution is made, 0.001 mile had been travelled. To compute the number of revolutions after 7.5 miles are travelled, the following proportion must be satisfied:
1 revolution / x revolutions = 0.001 mile / 7.5 miles
x = 7.5/0.001 = 7500 revolutions
