Answer:
The number 1 it's factor's are 1 and 0
The number 3 it's factor's are 0, 1, 3
The number 5 it's factor's are 0,1,5
Step-by-step explanation:
The answers for both the parts are as (a) the rate of proofreading is 7.5 pages per hour and (b) The payment received for each page is $2,.67.
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The pages proofread in 2 hours is 15.
The total amount received is $40.
(a) The proofreading rate can be known by dividing the total pages by total time as below,
Rate of proofreading = 15/2 = 7.5 pages per hour.
(b) As per the question the unitary method can be applied to obtain the payment for one page as follows,
Payment for proofreading 15 pages = 40
Thus, payment for proofreading one page is 40/15 = 2.67.
Hence, the proofreadingrate is 7.5 pages per hour and the average payment for each page is $2.67 respectively.
