Part A

  • 25%/100%
  • 1/4

Part B

  • 1 → 20 pieces
  • 4 → (20*4) pieces
  • 4 → 80 pieces of yellow paper

Answer:

See below ↓↓

Step-by-step 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
