For example. What percent is 5 of 25. Since 5 comes right after is, it is over the of portion. Since 25 comes right after of, it goes under the fraction bar. 5/25 = 0.2 Multiply by 100 to get the percent. 20%.

now hw do yu multiply a decimal
Stacey
  • Stacey
Decimals are multiplied like whole numbers, but we have to count the decimal places. For example: 0.5 * 8 5*8 = 40, but 0.5 has one digit after the decimal so we need one digit after the decimal in 40. 0.5 * 8 = 4.0 or 4

I get it

Another example: 1.25 * 0.02 125 * 2 = 250 With four decimal places 250 becomes 0.0250 or 0.025
anonymous
  • anonymous
okay so another example:O.8 * 15 15 * 8 =120 120=12.0
