yoloshroom · Answer

20% = 20/100 so .2
So mulitply all the numbers by .2 :)

kva1992 · Answer

exactly what yolo said

kva1992 · Answer

just make sure you round it to the nearest cent

campbell_st · Answer

here is a really easy method... 

move the decimal point 1 place to the left... that will be 10%

then double the answer for 20%

if you are working with money, you normally round to 2 decimal places

anonymous · Answer

i dunno how to round to the nearest cent... any chance u can help me with that? @kva1992

kva1992 · Answer

sure so if  you get 27.59 * .2  it will equal 5.518
so since 8 is above five you add one to the 51 and make it 52 which means your total is 5.52

kva1992 · Answer

does that make sense?

anonymous · Answer

kva1992 · Answer

where are you confused and ill try to explain it

anonymous · Answer

@campbell_st  when i did ur theory it just came out to 5.126

anonymous · Answer

@kva1992 8 is above five you add one to the 51 and make it 52 which means your total is 5.52. how does that work..

kva1992 · Answer

27.59*.2 is 5.518

anonymous · Answer

@kva i got that part.. but how does the 518 turn into 52. whats the logic behind it..

campbell_st · Answer

question 1.  10% = 2.759  so 20% =   5.518

anonymous · Answer

but campbell its going by money. 5.518$ wouldnt work..

campbell_st · Answer

so if its money  round to 2 decimal place   5.518  rounds to 5.52

kva1992 · Answer

so since you want to round to the nearest hundreds you would round 5.518 to 5.52 because 8 is above 5 so go to the nearest whole number

campbell_st · Answer

so the answer is $5.52

anonymous · Answer

ok so in simple terms take away the 8. since 8 is 1 number u add 1 to 51 that makes it 52?

kva1992 · Answer

If you want to round a number to the nearest hundred, the round off digit is the number in the hundreds' place. Look at the number to the right of the round off digit. If that number is less than 5, don't change the round off digit. If that number is 5 or more, add one to the round off digit

kva1992 · Answer

hopefully that explains it lol

campbell_st · Answer

well the rule for rounding... since its money, 2 decimal places is look at the digit in the 3rd dcimal place... 

if its 0,1 , 2, 3 or 4   no change the the digit in the 2nd decimal place

if its 5, 6, 7, 8 or 9   the digit in the 2nd decimal place goes up 1. 

so you had    $5.518    so look at 8, 3rd decimal place  apply the 2nd part of the rule

so the 1 goes up 1 to 2      so 5.518 rounds to 5.52
