I think it’s 4 off the bus and it’s a little too far away lol lol I got it on the bus now and I’m getting off the phone so I’m going on the road to go to church and I’ll park in the mail lol
He does not divide the numerator and the denominator by the same number. Nicholas divides 20 by 5 and 30 by 6. He ought to have divided 30 by 5 as well and then simplified.
P.S. Nicholas should have just divided both 20 and 30 by 10 to simplify in one step
