Step-by-step explanation:To write 24/30 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 24 by 30 what we write down as 24/30
First you must add the same numbers together, for instance, you wouldn't add 4y with 4 you have to add it with another number that is just like it, for instance 4y and 9y they are the same, so you can add them. So let's get to the problem now:
5y(2y-3)=(2y-3)
5y*2y=10y
(10y-3)=(2y-3)
You can do nothing to the other side because there are no numbers, that are the same.
Answer:
Percentage profit=40%
Step-by-step explanation:
Cost price=120 Naira
Sold price=168 Naira

=0.4×100
=40%
Percentage profit=40%
