Answer 1

I answered this question just some time back,
How we do this:
The same way:
m ÷ n
m = $1\frac{1}{4}$ 
n = 3

$1\frac{1}{4}$ ÷ 3
Change the mixed fraction into an improper one.
And multiply it by the reciprocal of 3 which is $\frac{1}{3}$

=$\frac{5}{4}$ × $\frac{1}{3}$
=$\frac{5}{12}$ 

Answer is F. $\frac{5}{12}$
