a. 20%

b. 15.3

c. 1900

d. 7.29

e. 180

f. 175

Way to do

a. 17 out of 85 how many percentage?

  • 17/85 × 100 = 20%

b. what is 17% of 90?

  • ? /90 × 100 = 17
  • ? /90 = 17 : 100
  • ? /90 = 0.17
  • ? = 90 × 0.17
  • ? = 15.3

c. 1026 out of ? = 54%

  • 1026/? × 100 = 54
  • 1026/? = 0.54
  • ? = 1026 : 0.54
  • ? = 1900

d. 8.1% of 90 = ?

  • 90 × 8.1/100 = 7.29

e. ?% of 50 = 90

  • 50 × ?/100 = 90
  • ?/100 = 90:50
  • ?/100 = 9/5
  • ? = 9/5 × 100
  • ? = 180

f. 88% of ? = 154

  • ? × 88/100 = 154
  • ? = 154 : 88/100
  • ? = 175
