12oz(8in^3orange/1.25oz)=76.8 in^3 of oranges...
Vo=(4p(3.5/2)^3)/3=22.45 in^3 per orange...
76.8 in^3(orange/22.45 in^3)=3.42 oranges...
Round down to 3 oranges.
One third is a rational number....since it can be written in p/q form(1/3)
So if the bakery is 1/10 of the shopping center's area, and the shopping center's area is 4500 feet, then the bakery's area is 1/10th of 4500 feet. 1/10th of 4500 feet is 450.
A more in-depth explanation:
A fraction is:
x/y
where y would equal how many parts you wanted to split a number into and x would equal how many parts you want to take.
So splitting 4500 into 10 parts and then taking one is basically 1/10 of 4500.
4500 in 10 parts, one would be 450.
We use rulers obviously because the length of rulers are about 4 more times longer than hands. Hope this helps you :]
