Answer:
D
Step-by-step explanation:
Divide and multiply
:)
We have n/5 = 18
to get the value of n, we need to get rid of the 5 in the denominator. to do so, we will multiply both sides of the equation by 5
(n/5)(5) = (18)(5)
n = 18*5 = 90
So how many does he have left
25-16=9
9 floors left
the want a percentage so 9 out of 25
percent is out of 100
a hack for this specific problem is that 25 is exactly 1/4 of 100 so
9/25 times 1=the same thing so
9/25 times 4/4 (simplifies to 1)=(9 times 4)/(25 times 4)
36/100
this is out of 100 so
36%
of course there is a legit way of solving this problem but this is a hack (this works for factors of 100 like 2,4,5,10,20,25,50)
