What fraction of 60 minutes is 10 minutes?
It is 10/60, which can be simplified, if required. No point in simplifying if you want to add up lots of fractions of an hour, though.
How do you calculate an average with fractions?
The same way you calculate averages with whole numbers: Add up all the fractions and divide by the number of fractions there are.
How does the fraction method help explain why you can line up the decimals and add digits with the same place values to find the answer?
Example, add 0.3 + 0.5, which equals 0.8...convert these to fractions and you see they both have the same denominator: 10 so, it would be the same as 3/10 + 5/10...since they have the same denominator adding the fractions topgether would be (3+5)/10 or 8/10. This is the same result as lining up the decimals and adding the digits: 0.3 + 0.5 = 0.(3+5) = 0.8
What two fractions add up to one half?
1/4 and 1/4
What do you do first with the mixed numbers before multiplying?
What you are to do is the mixed numeral is converted to a improper fraction. To do this just simply multiply the denominator with the whole number then add that with the numerator. With that number you end up with will be the numerator over whatever the denominator was. Then you can multiply the fractions.(I'm not a good explainer but i hoped i helped a bit)
