45% = 45 ÷ 5 / 100 ÷ 5= 9/20 (Answer)(ii) 2/3 can be converted into percentage form through multiply by 100 as -2/3 X 100 = 66.66% approx. (Answer)(iii) 22.50% can be written in fraction form as -22.50% = 22.50/10022.50% = 225 / 1000in simplest form, divide both numerator and denominator by 25 then,22.50% = 225 ÷ 25 / 1000 ÷ 25= 9 / 40 (Answer)(iv) 7/5 can be converted into percentage form through multiply by 100 as -7/5 X 100 = 140% approx. (Answer)So, the given has been completed as -FractionPercentage9/2045.00%2/366.66%9/4022.50%7/5140.00%b) A carton contains 150 cereal bars. What fraction of this number will each person get whendistributed to a class of 20 students?Solutions:Total number of cereal bars – 150Total number of students – 20So, each student will get -150 / 20 = 15 / 2 (answer).Question 4:Samuel paid cash for 3 discount-priced football tickets.
