Answer:
1 s / 6 s
Step-by-step explanation:
Since you have different units of measurement (seconds and minutes) you have to get them to be the same unit.
Change the 1 minute into seconds.
1 min = 60 sec
Now simplify the new fraction.
10 s / 60 s
10 can go into both the numerator and the denominator.
1 s / 6 s
50 pieces because when you do 25 times two fits you 50 fits witch can be reduced to 10
You would foil (x+1)(x+11)
x^2 + 12x + 11
