Explanation:
<em>Percentage</em> is defined as number of parts per 100.
Percentage can be expressed as a ratio (fraction) or decimal .
25% = 25 /100 = 1/4 = 0.25 50% = 50 / 100 = 1/2 = 0.5 75% = 75 / 100 = 3/4 = 0.75
You can use either the fraction or the decimal form to find the percentage.
This is how you apply this to questions a through d.
<u>a. 15% of 930 </u>
15% × 930 = 15 / 100 × 930 = 0.15 × 930 = 139.5
<u>b. 6% of 120 </u>
6% × 120 = 6 / 100 × 120 = 0.06 × 120 = 7.2
<u>c. 4.2% of 50 </u>
4.2% × 50 = 4.2 / 100 × 50 = 0.042 × 50 = 2.1
<u>d. 200% of 145</u>
200% × 145 = 200 / 100 × 145 = 2 × 145 = 290
