Jan has 500 pieces of paper. She prints as many copies as possible of a 16-page report. How many pieces of paper are left?
Rudiy27

Jan has 500 pages of paper.

She has a report of 16 pages.

But a report is printed on both sides of the page.

So the complete report shall be printed on 8 pages.

Now as the total pages are 500

We shall divide 500 by 8 and convert the simplified fraction to mixed no.

Now

\frac{500}{8} =\frac{125}{2} = 62\frac{1}{2}

So we shall be able to print 62 complete copies of the report which shall use 62 × 8 = 496 pages.

Number of pages left = 500 - 496 = 4 pages.

Ed is 7 years older then ted Ed's age is also 3/2 times ted's age how old are ed and ted ​
Rasek [7]

Answer:

if i'm right ted is 14 and ed is 21

Step-by-step explanation:

if ed is 7 years older than ted and is 3/2 times eds age, than we have to find out how much dose 2 represent in the equation 3/2 so we know that ed is seven years older than ted. so that means that if the equation 3/2 was 1/2, 1 would represent 7 years. (i hope your following me) so if 1 represents 7 than 2 must represent 14 and that would be the age of ted because in the equation 3/2 the 2 would represent teds age. and if the 2 represents teds age than 3 would be eds age. so 7 x 3 = 21.  (this is my first time answering a question so sorry if i'm confusing)
