If eight oranges cost 160 naira. Find the cost of five oranges?
If eight oranges cost 160 naira, the cost of one orange is 160/8 = <<160/8=20>>20 naira.
Therefore, the cost of five oranges is 20 x 5 = <<20*5=100>>100 naira. Answer: \boxed{100}.
To find the cost of five oranges, we need to determine the cost of one orange first.
Given that eight oranges cost 160 naira, we can set up a proportion to find the cost of one orange.
Let x be the cost of one orange.
We can set up the following proportion:
8 oranges / 160 naira = 1 orange / x naira
To solve for x, we cross-multiply:
8x = 160
Now, we divide both sides of the equation by 8 to isolate x:
x = 160 / 8
x = 20
Therefore, the cost of one orange is 20 naira.
To find the cost of five oranges, we can simply multiply the cost of one orange by 5:
Cost of 5 oranges = 20 naira/orange * 5 oranges = 100 naira.
So, the cost of five oranges is 100 naira.
To find the cost of five oranges, we need to determine the cost of one orange first.
Given that eight oranges cost 160 naira, we can set up a proportion using the number of oranges and their cost:
8 oranges / 160 naira = 1 orange / x naira
Now we can solve for x, which represents the cost of one orange:
8x = 160
x = 160 / 8
x = 20 naira
So, the cost of one orange is 20 naira.
To find the cost of five oranges, we multiply the cost of one orange by the number of oranges:
Cost of five oranges = 20 naira/orange * 5 oranges
Cost of five oranges = 100 naira
Therefore, the cost of five oranges is 100 naira.
