Percent of a Number 2.7p. 147 15 30 We created equivalent
ratios.By doubling the 100 to 200, we just had to double the first
terms in each of the ratios. 30 17 34 34 15 30 30 18 36 36 12 24 24

18 No snack 22 Total 100 200 46 30 34 36 44 ( x2) In this ratio
tables, instead of using the % sign, you see the total of 100 is
used. = = Lets talk about the values represented on this bar.
10% of 300?? 30 Half of this???? 15 15% = 10% + 5% 18% of 300 =
.18(300) = 54 (3) (3) = Which number represented the part? Which
number represented the whole? Percents greater than 100 or less
than 1
145% of % of % of 58 1.45(320) = 2.20(65) = .0025 (58) = .145 464
143 Which number represented the part? Which number represented the
whole? Which number represented the part?
Which number represented the whole? 145%= ? 100% of 320 would be
320. More than 100% of a number will be greater than the number. 29

Which number represented the part? Which number represented the
whole? 143 143 x 600 =n 1.28 x 550 =n .003x 200 =n = 5.1 = 704 = .6
Which numbers represented the parts? Which numbers represented the
whole? Which numbers represented the parts?
The decimal multiplication method is the best for these values.
1.28 x 550 =n x 600 =n .003x 200 =n = 5.1 = 704 = .6 Which numbers
represented the parts? Which numbers represented the whole? 20%, or
1/5 of the 70 players competed in soccer.What is 1/5 of 70? What is
15% of 20? .15 x 20 = ?? = 3 students
Which number represented the part? Which number represented the
whole? .32 x 60 = x 220 = x 4 = 19.2 1.21 11 32(60) 100 Can anyone
think of this in a different way? 32(6) 10 = = Which number
represented the part? Which number represented the whole? There are
several ways, but they one you will use most often is:
Write the percent as a decimal Multiply the decimal (part)by the
other number (whole) to find the missing part.
