The sum of three consecutive natural numbers is 651, find the numbers.

3*7*31
21*31=651

Another Question I had problems with was :Your weekly paycheck is 25 percent less than your coworker's. Your two paychecks total 780. Find the amount of each paycheck.

let a equal the amount of the paycheck
25% of my paycheck is a*25%
coworker=a(a*25%)=a+(a*25%)=a*(25a/100)=a+(a+4)=4a+a/4=5a/4

780a+5a/4=780
4a+5a=3120
9a=3120/9
a=346

1. If the numbers are
x-1,x,x+1, then

3x = 651
x = 217

So, the numbers are 216,217,218

Don't know what was all that stuff with factors of 651. Looks like you need to study what "sum" and "consecutive" mean.

The two paychecks are p and .75p. So,
p + .75p = 780
1.75p = 780
p = 445.71
Your paycheck is 25% less, so it is 75% of the other. Once you got your answer, did you check to see whether it worked to satisfy the given conditions? That pseudo-algebra you threw up is meaningless.
