Answer:
See below ↓↓
Explanation:
Part A
We have to write
25%
as a
rate per 100
⇒ We know percentages are given to be
the fraction of a number out of 100
⇒ Therefore, 25% as rate per 100 =
25/100
⇒
1/4
[simplified]
Part B
Let's take the
total number
of pieces of colored paper to be T
Then 25% of T is 20
Therefore our equation will be :
⇒ T x 25/100 = 20
Bring 100 to the other side
⇒ 25T = 2000
25 is a factor of both 25 and 2000, so it cancels out, and we are left with :
⇒ T = 80
There are
80
pieces of paper
