Target Board 6

QuestionsUsing the first three rows of the target board answer the following questions. 1. Find two percentage numbers that total 100%. 2. Change each percentage to fractions. 3. Change each percentage to decimals. 4. Find 10% of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. 5. Find all these percentages (on the board) of 60. First find 10%: 10% of 60 = 6 therefore 5%=3. 80% of 60 = 8 x 6 = 48. 65% will be 60% + 5% = (6 x 6) + (3 x 1) = 36 + 3 = 39. 6. Using the last row of the target board find the following percentages of a number by:

first finding 10%, then halving and halving again to find 212%

e.g. find 1212% of 60:

10%= 6, 5%=3, 212%= 112, therefore 121

2% = 6 + 112 = 712
