You look at the first decimal number after the ones place. If it's less than 5, then you leave the percent as it is; but if it's greater than or equal to 5, then you round up. Eg. 56.4% = 56% 56.6% = 57% 4 or below let it go 5 or above give it a shove
Number*percent in a decimal 200 * .42 = 84
4/90 x 100 = 4.4 recurring (that is, 4.4444..) percent.
It is: (68/80)*100 = 85%
340 is 39.6% of 859
22.2 is 28.3% of 78.57
2,760/276 = 10 = 1,000%
144/300 = 0.48 = 48%
46.7 divided by 3.15 and round to the nearest tenth
round 53 to the nearest tens place

35,682 = 36,000 281,035 = 281,000 36,000+281,000 = 317,000
Round your factors to the nearest 10's, 100's 1000's, etc. Then multiply. You should be able solve the problem more or less in you head. If you need to use a pen and paper, you must round to and even higher place. When rounding, if the place your rounding ends in 1-4, you round down. 5-9= round up. For example: 14 rounded to the nearest 10 =10. 16 rounded to the nearest 10=20. 123 rounded to the nearest 100= 100. 191 rounded to the nearest hundred= 200.
That depends on what the question is. A percent is just a number. You're asking "How do you solve a number?"
42.86% to solve this: 3 divided by 7 is equal to 0.428571428... (it is never ending or irrational) then you multiply the decimal by 100, or move the decimal point to the left two digits. you will get 42.8571428... round to the nearest hundredth ( depends on what decimal place you want to round it to) 42.8571428... The digit after 5 is greater than 5 so you round up to get 42.86. add the % and you're done! Source: My brain.
