Q=5. The total number of blue and red cars in a parking lot are 1650. 70% of the cars are
blue. How many cars are red?
Answers
Answer:
1155
Step-by-step explanation:
Hello! Let's do your problem.
What do we know?
We know that the total number of cars in the parking lot is 1650.
We also know that 70% of those cars are blue.
What do we need to know?
We need to know the amount of red cars.
How do we find the amount of red cars?
So, we need to find 70% of 1650. How do we do that? Well, I'll put it into steps for you to understand.
Step 1: Our output value is 1650.
Step 2: Let x represent the unknown value.
Step 3: From step 1 above, 1650 = 100%.
Step 4: Similarly, x = 70%.
Step 5: This results in a pair of simple equations:
$1650=100%(1).
x = 70%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
1650/x = 100%/70%
Step 7: Again, the reciprocal of both sides gives (we're basically flipping the fractions)
x/1650 = 70/100
=> x = 1155$
Thus, 70% of 1650 is 1155
That's pretty much it! Good luck solving equations like this one! I hope this helps you and I hope you have a great day :^)
