Solve the following proportion. x/10 = 4/8

One way to go about this is cross multiplication: multiply both sides by both denominators to remove the denominators.

x/10 = 4/8
x/10 * 10 * 8 = 4/8 * 10 * 8
8x = 40

Now the equation is in a form you can solve easier.

8x = 40
x = 5

Wow. that is a really cool question.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
