Yes, If the two numbers have no factors in common then they are relatively prime.
Answer:
x=155
Step-by-step explanation:
I hope the pictures are clear and you get the concept!
Do PEMDAS! Multiply and divide from left to right. 123456789 x 125 is 15432098625, and now we divide by 4, giving us 3858024656.25, but rounded to the nearest whole number (ones) is 3858024656.
Hope this helped!
