I'll give you a formula and you use it any time you need to change a fraction into a percentage, okay?
2/5 x 100/1
you put your fraction first, then times it by 100/1
btw, if you want the answer, its 40%
To convert any number to a percent, multiply by 100%.
2/5 = (2/5)*100% = (200/5)% = 40%
2/5 = .4
to convert it to % multiply by 100
= .4*100 = 40 %
I really suck at math, but I think I can get this one. Find a common denominator, like you have 2/5 the next number they both go into is 10. So 2 fives make ten. Then you have to multiply the 2 by the same 2 like you did with the 5. This will give you 4/10, the four is four of ten, so the percent is 40%, if you add a zero to both numbers 40/100, we know that is 40%. Percents are easier for me, because I worked as a waitress, and we know how much our tip should be according to the service we gave, and the percents.
To convert any fraction into a percentage simply multiply by 100.
2/5 x 100 = 40%
2/5 doubled would be 4/10 so this would translate to .04
Convert 2/5 to a decimal (0.40), move decimal point two places to the right (40), and you end up with 40%
Convert 3 4/5 to a percent
