remember
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
invert and multiply
first convert to improprer fraction in form a/b
4 and 1/4=4+1/4=16/4+1/4=17/4
7/10=7/10
4 and 1/4 divided by 7/10=
(17/4)/(7/10)=
(17/4)(10/7)=
(1710)/(47)=
170/28=
85/14
convert to mixed
85/14 is about 6
6*14=54
85/14=84/14+1/14=6+1/14=6 and 1/14
