Sir/mam can you please tell me how to solve some numericals on cross m...
It is easy like 5/2= 4/3
5 multiply 3 and 4 multiply 2
15 = 8
15-8=0
7 ans
if you don't understand then simply transpher 2 which is in division to other side by changing sign to multiply do same with 3 and you get your answer
hope this helps
try solving this 9/13= 24/6

Cross Multiplication Method:
The cross multiplication method is used to solve linear equations involving fractions. It is a simple and efficient method that helps in finding the value of the unknown variable.
Procedure:
1. Identify the equation: Write down the given equation.
2. Clear the fractions: Multiply both sides of the equation by the least common multiple (LCM) of the denominators to eliminate the fractions. This step helps in simplifying the equation.
3. Cross multiply: Cross multiply by multiplying the numerator of the fraction on the left side with the denominator of the fraction on the right side, and vice versa. This step helps in obtaining a linear equation.
4. Simplify: Simplify the equation obtained after cross multiplication.
5. Isolate the variable: Rearrange the equation to isolate the variable on one side.
6. Solve for the variable: Solve the linear equation by performing the necessary operations to find the value of the unknown variable.
Example:
Let's solve the following linear equation using the cross multiplication method:
2/3x + 1/4 = 3/5
Step 1: Identify the equation: 2/3x + 1/4 = 3/5
Step 2: Clear the fractions: Multiply both sides of the equation by the LCM of the denominators, which is 60.
60 * (2/3x + 1/4) = 60 * (3/5)
Step 3: Cross multiply:
(60 * 2 * x) / 3 + 60 * 1 / 4 = (60 * 3) / 5
Step 4: Simplify:
40x + 15 = 36
Step 5: Isolate the variable:
40x = 36 - 15
40x = 21
Step 6: Solve for the variable:
x = 21 / 40
Therefore, the value of x is 0.525.
Conclusion:
The cross multiplication method is a useful technique to solve linear equations involving fractions. By following the steps mentioned above, the unknown variable can be determined. Remember to simplify the equation and isolate the variable before solving for it. Practice numerous examples to gain proficiency in using this method.
