Tutor teaches about the direct proportion for the students. In mathematics, direct proportion is one of the most important topics. Direct proportion is in the form of ratio. Also direct proportion is in the form of fraction format. Direct proportion is always equals to the constant value. Example: If the A factor changes means then the B factor also change. There are number of online problems is given for the direct proportion. In this article we are going to solve the direct proportion.
Explanation to direct proportion tutor
Tutor explanation for direct proportion:
The explanation give by tutor for direct proportion is given below the following section,
Direct proportion is always in the form of,
x/y = z
where,
x and y is known as the values.
z value is used for defining the constant function.
Example problems to direct proportion tutor
Problems given by tutor for direct proportion:
Example 1: Solve: If 20 liters can travel 120 kilometers, then find how long it will take for 30 liters.
Tutor Solution:
Step 1: Given:
20 liters = 120 kilometers
30 liters = ? kilometers
Step 2: Assume:
Unknown = a
Step 2: To find:
20/30 = 120/a
Step 3: Solve:
20 xx a = 120 xx 30
20a = 3600
a = 3600/20
= 180
Tutor Result: 20 liters = 180 rupees.
Example 2: Solve: If 30 liters can travel 150 kilometers, then find how long it will take for 50 liters.
Tutor Solution:
Step 1: Given:
30 liters = 150 kilometers
50 liters = ? kilometers
Step 2: Assume:
Unknown = a
Step 2: To find:
30/50 = 150/a
Step 3: Solve:
30 xx a = 150 xx 50
30a = 7500
a = 7500/30
= 250
Tutor Result: 50 liters = 250 rupees.
My forthcoming post is on Rounding with Decimals and cbse sample paper class 11 will give you more understanding about Algebra.
