Hitler had dark blue eyes that ran in his family but not enough info on his family having any blonde hair.

Eva Braun had pale blonde hair and blue eyes and it did run in her family.

I don't know! What I do know is to compare fractions with same denominators and convert with form of one. 40 is the common denominator here.

2*3/2*20 = 6/40

5*1/5*8 = 5/40

------So,

3/20 is larger than 1/8

There a couple of ways to do this.  You can write them with a common denominator and compare.

3/20 = 6/40  and    1/8 = 5/40

6 > 5 , so yes.

Or, convert them to decimals and compare.

3 divided by 20 is 0.15    and    1 divided by 8 is 0.125

0.15 > 0.125 , so yes.
