What is the greatest positive three-digit integer that is divisible by 5, 7 and 9?

First, we want to see what the product of the three numbers is:

9 * 7 * 5 = 315

From there, we can find multiples of 315 to get the largest 3- digit number divisible by 9, 7, and 5.

315, 630, 945, 1260...

The largest is 945.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
