4/5=0.8=80%
27/100=0.27=27%
3/20=0.15=15%
8/9=0.88=88%
9/1000=0.009=00.9%
21/50=1.42=142%
8/9 = 0.88889 = 89%
The last one is wrong. The others are correct.
For the last one, 142% becomes 1.42 and then 1 42/100?
21/50 is less than 1.
How did you get 142%?
Well in this paper they only give the percent and you have to figure out the decimal and fraction.
The percent they gave is 142%.
142% = 1.42 = 1 42/100 = 1 21/50
To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). To convert a decimal to a percentage, multiply it by 100. Let's go through the calculations for each example:
1. 4/5: Divide 4 by 5, which equals 0.8. Multiply 0.8 by 100, which equals 80%. Therefore, 4/5 is equal to 0.8 or 80%.
2. 27/100: Divide 27 by 100, which equals 0.27. Multiply 0.27 by 100, which equals 27%. So, 27/100 is equal to 0.27 or 27%.
3. 3/20: Divide 3 by 20, which equals 0.15. Multiply 0.15 by 100, which equals 15%. Thus, 3/20 is equal to 0.15 or 15%.
4. 8/9: Divide 8 by 9, which equals approximately 0.88888 (repeating). Multiply 0.88888 by 100, which equals 88.8888%. Rounded to the nearest whole number, 8/9 is equal to 0.88 or 88%.
5. 9/1000: Divide 9 by 1000, which equals 0.009. Multiply 0.009 by 100, which equals 0.9%. So, 9/1000 is equal to 0.009 or 0.9%.
6. 21/50: Divide 21 by 50, which equals 0.42. Multiply 0.42 by 100, which equals 42%. Therefore, 21/50 is equal to 0.42 or 42%.
