2007-04-29 02:04:38 · 9 answers · asked by J B 1 in Science & Mathematics ➔ Mathematics
1% = 1/100
Thus
89% = 89/100
40% = 40/100 = 2/5
5% = 5/100 = 1/20
______
0.01 = 1/%
Thus
1/8 = 1÷8 = 0.125 = 12,5%
5/6 = 5÷6 = 0.833 = 83,3%
_____
2t + 5= 53
subtract 5 from both sides
2t + 5 - 5 = 53 - 5
2t = 48
divide both sides by 2
2t÷2 = 48÷2
t = 24
_____
Hope this helps.

percent literally means "each hundred" so x% is x in each hundred or x/100
89% = 89/100
40% = 40/100 = 4/10 = 2/5
5% = 5/100 = 1/20
to find percent from a fraction, find the decimal value, and multiply by 100
1/8 = 0.125 = 12.5%
5/6 = 0.833333(recuring) = 83.33%
2t +5 = 53t
2t = 53-5 (take 5 from both sides)
2t = 48 (simplify)
t = 48/2 (divide both sides by 2)
t = 24
as a percent 2400%

Write each percent as a fraction => put % over 100 and cancel if possible.
40% = 40/100 = 2/5.........divide top and bottom by 20 top and bottom by 20
Write each fraction as a percent => X by 100/1
5/6 = 5/6 X 100/1%
5/6 = 500/6%..........X top by top & btm by btm (or cancel)
5/6 = 250/3%..........divide top and bottom by 2
5/6 = 83 1/3 % 83.33.... 250 divide by 3

2t + 5= 53

*********************************
1. 1/8 = 1/8*100 = 25/2
2. 5/6 = 5/6*100 = 250/3
*********************************
1.2t + 5 = 53 t= _______
2t + 5= 53
subtract 5 from both sides
2t + 5 - 5 = 53 - 5
2t = 48
divide both sides by 2
2t÷2 = 48÷2
t = 24
