I hope this is what you were looking for.
To solve this problem we can think of a rule of three.
Writing the rule of three we have:
3 ---> 2
x ----> 18
Clearing the value of x
x = ((18) / (2)) * (3) = 27
answer
zak will take 27 steps if rich takes 18 steps
(2/5) of (1/3) means to multiply.
(2/5)*(1/3)= 2/15
7x10x and use yout braing
