### Percent Scribe for January 26, 2010

5. a) 2/5% of 325 = 1.3
2/5% = 0.4%
First find 1% of 325. Do that by dividing 325 to 100 and you will get 3.25, then divide it again by 10 to get 0.1% (0.325) multiply 0.325 by 4. The answer is 1.3

b) 15 1/4% of 950 = 144.88
Find 10% of 950, 950÷ 10 = 95 (10%), divided it into half so 95 ÷ 2 = 47.5 (5%), 95 + 47.5 = 142.5.
950 ÷ 100 = 9.5 (1%) ÷ 4 = 2.375 (1/4%)
142.5 + 2.375 = 144.88

c) 175% of \$125.50 = 219.63
100% is 125.50 ÷ 2 to get 50%.
125.50 ÷ 2 = 62.75 (50%) divide it into 2to get 25%
62.75 ÷ 2 = 31.375(25%)
125.50 + 62.75 + 31.375 = 219.63

6. a) 5/8 of 520 = 3.25
5/8 = (0.625)
520 ÷ 100 = 5.2 (1%) ÷ 2 = 2.6 (0.5%) ÷ 2 = 1.3 (0.25%) ÷ 2 = 0.65(0.125)
2.6 + 0.65 = 3.25

b) 75 2/5% of 200 = 150.8
divide 200 by 4 to get 25%! 200 ÷ 4 = 50(multiply 50 by 3) 50 x 3 = 150 (75%)
divide 200 by 100 to get 1%! 200 ÷ 100 = 2(1%) (divide by 10) 2 ÷10 = 0.2 (0.1) multiply by 4 to get 2/5%. 0.2 x 4 = 0.8
150 + 0.8 = 150.8

c) 250% of \$76.50 = 191.25
Multiply 76.5 by 2. 76.5 x 2 = 153(200%)
divide 76.5 by 2. 76.5 ÷2 = 38.25
