need help finding the fraction of a mixed number STAT

My son as well as I need help. I can find the fraction of a num like 1/4 of 20 that is easy it's 5.

What I am having problems with is finding the fraction of mixed numbers like 1/4 of 5 3/8.

Any help would greatly be appreciated.
thanks

my math may be rusty but I hope this is right
If you are using a calculator
5 3/8 = 5.375 ( 3/8= .375)
5.375 * 0.25 = 1.3475

converting fractions
5 3/8 = 43/8
43/8 * 1/4 = 43/32
= 1 11/32

Using the calculator 11/32=0.3475. It works

reported as a proper fraction 5 3/8 divided by 1/4 = 43/8*1/4= 43/32 = 1 and 11/32 remainder.

I come up with the same with my rusty math. The 43 is from breaking down to 1/8 ths. 5 x 8 is 40 + the 3 is 43/8.

1/4 of 20 = 1/4 x 20/1 = 20/4 = 5

1/4 of 5 3/8. = 1/4 x 43/8 = 43/32 = 1 11/32

-- yep got the same :wink:

Must be boredom here, or scratching old brains. I e-mailed son the HS math teacher and he confirmed my suspicions.
Do we get a check/done for the homework?!

Awww.... I got here too late for the party! This stuff is fun! :) So yeah every one is right. You deal with the mixed number by unmixing it. Convert the 5 in 5 3/8 into 8ths = 40, so 5 3/8 = 43/8 ths. Then you can do whatever you need to with it. One fourth of 43/8ths = 43/8 divided by 4 = 43/8x4 = 43/32 = 1 and 11/32.
