The fraction 8/21 cannot be simplified because the numerator and denominator don't have a common factor except 1.
It’s B. because 6•6=36 and B shows a little over six so B would be your answer.
10 * 6 = 60 by the time Zach joins so 125-60 = 65
Now 6 (lexie) +7 (zach) = 13 (together) and 65/13 = 5.
6*5 = 30 and 7*5 = 35. 35+30 = 65
Your answer is 5.
This is how it would look like, hope that this is not too late to help you yet!
Have a great day!
