since the cross multiples are equal, you find a product and use the inverse operation as you would in an equation
Example 4 is to 36 as 3 is to X: 4/36 = 3/X --> 4*X = 3*36. Divide both sides by 4, to solve for X = 27.
is over of = percent of 100
is/of=%/100
What is 10% of 40.
is = x
x/40 = 10/100
cross mulitply 40*10= 400/100=4 x=4

2x divided by 7 equals 11 solve for x?
2x/7 = 11 Multiply both sides by 7: 2x = 77 Divide both sides by 2: x = 77/2 = 38.5
To solve 5x 65 you must both sides by 5?

Solve the system by the elimination method 7x-9y equals 35 plus -3x plus 6yequals -15?
7x - 9y = 35-3x + 6y = -15 (divide the second equation by 3, after that multiply it by 7)7x - 9y = 35-7x + 14y = -35 (add both equations)5y = 0 (divide both sides by 5)y = 07x - 9y = 35 (substitute 0 for y)7x = 35 (divide both sides by 7)x = 5Thus the solution of the given system of the equations is x = 5 and y = 0.
When do you cross multiply to solve an equation?
When doing fractions, you may cross multiply.
How do you solve a scale factor problem?
cross multiplacation. put the 3 numbers into fractions and than multiply the 2 diagnol numbers then divide by the third.
How do you solve proportions using cross products?
say it is 1 over 2 is equal to x over 4 you multiply 4 and 1 then 2 and x and you get 4=2x. Solve for x = 2. So the equivalent proportion is 2/4.
How do you solve proportions?
To solve proportions, you need to set up a ratio equation where two ratios are equal to each other. Cross-multiply by multiplying the numerator of the first ratio by the denominator of the second ratio, and vice versa. Then solve for the variable by dividing both sides of the equation by the coefficient of the variable. Finally, check your solution by plugging it back into the original proportion to ensure it balances.
