- Hey Nat, are you free to help me with my math work? I still don’t understand what is direct proportion..
- Yea sure, but Im going out later in a bit so it has be quick..
- To solve this, first, you need to write the right equation and that direct proportions are solved using the equation, a = bc.
- Heres an example: Let’s say a cake contains 2 eggs. How many cakes can you make with 6 eggs?
- Then, You use the information given in the problem to find the value of b. In this case, you need to find b when c = 2 and a = 1.
- THE END.
- Yes, your right!
- Then we rewrite the equation from step 1 substituting in the value of a found in step 2?
- Then 1 = b x 2 , 14 = b Therefore, a = 14c is the direct proportion equation.
- After doing the step 2, We can now proceed directly to solving the problem.
- So, the answer is 6.
- You’re welcome, now I’ve got to go out.. see you tomorrow in school!
- Ohh, thank you Nat! I understand now! Thank you!
