convert 1/2 to a percent?

Question

Translate the following statement into an algebraic equation. Let x represent the number. 12 less than 5 times a number is 18

Ching leaves San Francisco and travel toward San Francisco at 50 mi/hr., an hour later, Phil leave Los Angeles and travel toward San Francisco at 60 mi/hr. If the two cities are 380 miles apart, how many hours will it take for Ching to meet Phil

Answer 1

Divide 1 by 2 to obtain the decimal

1 / 2 = 0.5

Multiply the decimal by 100 and attach the percent sign %.

0.5 x 100 = 50 %

The answer is 50 %

- - - - - - - - - - -

5x - 12 = 18

5x - 12 + 12 = 18 + 12

5x = 30

5x/5 = 30/5

x = 6

The answer is x = 6

- - - - - - s-

Answer 2

5x-12=18

Ok if Ching leaves San Francisco and travels toward San Francisco he's already there.. so all he has to do is wait on Phil.. which takes 6 hours and 20 minutes.. but lets assume Ching ain't in San Fran.. well it will take him 7 hours and 48 minutes. Phil will have to wait 28 minutes for Ching to arrive given that he is leaving an hour later.

And 1/2 is 50%.

Answer 3

Q 1. .5 = 1/2 as a percent

Q 2. 5x - 12 = 18
+12 +12
5x = 30
x = 6

Q 3. I have never been good at doing these problems, so I won't attempt it... :-)

Answer 5

You can convert any fraction to a percent by dividing the top number (numerator) by the bottom number (denominator). .

1 ÷ 2 = .5

Convert the decimal to a percent by multiplying by 100--move the decimal point two spaces to the right. (Add zeros if necessary.)

.5 = 50%

Answer 6

1/2 = 50%
<>
12 - 5*x = 18
-5x = 18 - 12
-5x = 6
x = 6/5
x = 1,2
