Express 20% as a fraction show me the working

1/5

Step-by-step explanation:

Lets start with the number 100. We know that 1/10 of 100 is 10! 1/10 can also be written as 10%.

Now lets think about it, We're looking for 20%. If 1/10 of 100 is 10%, then 2/10 of 100 is 20%!

So you've got the fraction 2/10! Now you need to simplify it :)

Both the numerator (2) and the denominator (10) can be divided by 2!

(2/2)=1

(10/2)=5

Therefore, after simplifying 2/10 your final answer should be 1/5!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
