First you have to know that dividing by 9/18 is the same as multiplying by 18/9.
So you have (1/3)/(9/18) = (1/3)*(18/9) = 18/(3*9)
you can simplify by 9
= (2*9)/(3*9)
=2/3
five eighteenths
6/18 = 1/3 (one third)
nine eighteenths is one half. Half of 6/7 must be 3/7
one third. 6 / 6 = 1 -- -- 18 / 6 = 3
One third divided by two and one third = 1/7
One half is nine eighteenths. Nine eighteenths minus three eighteenths is six eighteenths, which is also one third.
13 eighteenths
27
yes
Four ninths.
2/27
One third divided by one ninth is the same as one third times nine, which is three.
five eighteenths
one third, six eighteenths, twelve thirtysixths...
6/18 = 1/3 (one third)
nine eighteenths is one half. Half of 6/7 must be 3/7
Nine eighteenths is the same as one half. It's like 9 out of 18, and 1 out of 2.
