hard

i think:

P-Pat

K-Kate

P=K

Pat and Kate shared some stamps. Pat then gave 2/5 of what she had. How many more percent did Kate have than Pat in the end? (Round off to the nearest whole number.)

P-2/5P=3/5P (how many Pat left)

2/5P=2/5K

K+2/5K=7/5K(Kate s stamps whith 2/5 Pats)

Pat then gave 2/5 of what she had. How many more percent did Kate have than Pat in the end?

Let s found how many percent of P is K

(7/5)/(3/5) = 2.3333333333333333=2.33(aprox)

to find how many more percent:

233-100=133

Answer:133

Le't see.....if they shared some stamps, I'm going to assume that they had an equal number of them to start with......call this N........so the total they started with was 2N

After Pat gave 2/5 of what she had, she has N - (2/5)N =  (3/5)N

And Kate must now have  N + (2/5)N  =  (7/5)N

So......

Pat had   (3/5) N  of the total, 2N   =  3/10N  = 30% of the total

And Kate had    (7/5)N  of the total, 2N  =  7/10 N =  70% of the total

So.....Kate had 40% more than Pat
