Dividing a fraction by a whole number Video Lecture | Advance Learner Course: Mathematics (Maths) Class 6

let's say we have two thirds all divided
by five and this is exactly the same as
two thirds divided by five and many of
you might get confused when you divide
by a whole number but that whole number
is actually a fraction as well the five
can also be written as 5 over 1
anytime you divide by one it doesn't
change anything so now in order to
divide these two fractions I'm going to
multiply by the reciprocal of 5 over 1
so the reciprocal of 5 over 1 is just 1
over 5 so now I can multiply the two
numerators 2 times 1 is just 2 and 3
times 5 is just 15 so now let's just go
over one more example so let's say we
have 6 all divided by 3 over 2 this can
also be written as 6 divided by 3 over 2
and once again if you get confused by a
whole number of 6 you can actually
change it into a fraction 6 is the same
thing as 6 over 1 so now to divide these
two fractions we just have to multiply
by the reciprocal so 6 divided by 3 over
2 is the same thing as 6 over 1
multiplied by the reciprocal of 3 over 2
which is just 2 over 3 now we can
multiply these two fractions together 6
times 2 in our numerator gives us a 12
and we have a 1 times 3 in our
denominator which just gives us 3 and of
course 12 over 3 can be reduced both
numbers can be divided by 3 evenly so
I'm going to divide the 12 by 3 and
whatever you do to the top you have to
do to the bottom in our numerator we
have 12 over 3 which is just 4 and in
our denominator we have 3 divided by 3
which is just 1 and 4 over
is just four so here are some more
videos with some more example problems

I really hope you're finding my
tutorials helpful so until my next video
I will see you later
