Question

how do architects use fractions, decimals, and percentages???????????

Answer 1

1/2 is the same as .5 and 50%

2/5 is the same as .4 and 40%

fractions, decimals and percentages are all interchangeable, however percentages are generally just used in charts for a marketing group to understand (they like percents better).

Answer 2

When you are converting fractions to decimals and vice versa then you turn all of the fractions into decimals and leave the ones that are already decimals alone.
0.75,0.70,0.14
