Question

Landon puts 30.5% of his paycheck in his savings account. What decimal is equivalent to 30.5%

Answer 1

0.305

Explanation:

When we use the percentage (%) notation, to express for example the happening of a success is X%, we are expressing that the corresponding fact is happening X times every 100 times. Instead of X% we could use X/100.

In this example, every 100 units of his payment check, Landon takes 30,5 unites and puts them to his saving account. So, instead of 30.5% we could say 30.5/100. (30.5% = 30.5/100).

So, we have:

30.5% = 30.5/100 = 0.305

This way, 0.305 is the decimal equivalent to 30.5%.

Observation: For avoiding comas in the latter fraction we could also say: 305/1000.
