Explanation Given Information: The available jobs in the new President’s administration are 7 , 000 and the applicants are 300 , 000 . Formula used: Cross multiplication method: To solve the proportional problem by using cross multiplication, follow the steps as mentioned below. Step 1: Represent the unknowns by a letter. Step 2: Set the proportion with one ratio, expressed as a fraction on both side of the equal sign. Step 3: Multiply numerator of the left side ratio with the denominatior of right side ratio and place the product on one side of the equal sign. Step 4: Multiply denominatior of the left side ratio with the nominatior of right side ratio and place the product on other side of the equal sign. The step 3 and 4 together is called as cross multiplication. Step5: Solve for the unknown value. Calculation: Consider that the available jobs are 7 , 000 and the applicants are 300 , 000 . Suppose that X be number of people applied for the job. The proportion is 300,000 applicants is to 7,000 jobs equals X applicants is to 1 job, 300 , 000 7 , 000 = X 1 Apply cross multiplication, this gives, ( 300 , 000 ) 1 = ( 7 , 000 ) X Or, it can be written as: 7 , 000 X = 300 , 000 This equation represents that X is multiplied by 7 , 000

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
