73% you move the decimal point two times to the right to find the percentage
Answer:
1, because 13 does not divide by anything by 1 that 20 dived to also
If you are saying:
(3/12) - (8/12)
Then since their denominators are the same we can subtract the numerators to get our answers.
3 - 8 = -5
Following the rule of adding and subtracting fractions, the denominators will not change unless they are different.
So: (3/12) - (8/12) = -5/12
Average =total sum of all the numbers / number of items in the set.
In other words, to find the average, add up all of the numbers in the set, and then divide by however many items you have.
A.
Test scores: 78,83 and 79
average =(78+83+79)/3 = 80
B.
weights : 2 lb, 5 lb, 7 lb, 5 lb, 9 lb, and 8 lb.
average = (2 lb+ 5 lb+ 7 lb+ 5 lb+ 9 lb+ +8 lb)/6 = 36/6 = 6lb
