In a parking lot, 48% of the cars have a gps. express this percent as a fraction and a decimal.

Hello! 48% can be expressed in multiple ways, and I'll explain how to convert it.

Fraction: To convert a percentage into a fraction, put the number over 100 and simplify if necessary.

48/100= 24/50= 12/25

Decimal: To convert a percentage to a decimal, move the decimal two places to the left. 48% : 48. 4.8, 0.48

Hope this helps! :)

5m/20 steps =?/1000 steps 
You have to use ratios at first to determine the unknown  

then divide 1000 by 20 to get the multiplying factor which is 50, now you multiply 50 by 5m to get the unknown in meters, there you just convert meters to km. 50x5 = 250 meters, 250 meters = 0.25km . At this rate, William will run .25 km after taking 1000 steps.
