Just round the two numbers
$285 and $305 are close to 300
multiply 300 by 15 to show how much he earns in 15 days.
300 x 15 = 4,500
$4,500 is my answer
idk if its correct tho
hope this helps :)
The only number that can be for both is 1. This is mainly because 7 is a prime number meaning only 7 and 1 can go into it. 6 can be divide by 2 and 3 also, but these aren't common. Therefore it would have to be 1.
The greatest common factor of 12 and 15 is 3 because it is the greatest number divisible by both 12 and 15.
