56/x = 7/9 ??? How do I do this problem??

Answer 1

Cross multiply.
56 * 9 = 7 * x
504 = 7x
504/7 = x
72 = x

Answer 2

Divide 7 into 56 - this gives you 8. So you know that the fraction is 8 times bigger than 7/9 on the top and the bottom. Multiply 9 times 8 and get 72.

So 56/72 = 7/9

Hope that helps

Answer 3

56 x 9 divided by 7 = 72

Answer 4

You cross multiply

56/x = 7/9

7x = 56*9

7x = 504

x = 72

Then check your answer
Find the least common denominator which is 8 and divide 8 into 56 and 72. If you get 7/9 then the answer is right.

56/72 divided by 8/8 = 7/9

Answer 5

you have to ask yourself what number times 7 is 56 (8). Then multiply 9 times 8 and you get 72. That means x=72

Answer 6

56/7 = 8

Mulitply 9 x 8 = 72

x = 72

Answer 7

Do cross multiplication. 56(9) = 7x. To get x divide both sides by 7. x = (56)(9)/7

Answer 8

You would multiply 56 by 9 and get 504, then take the 504 and divide it by 7 and get 72 therefore x=72

Answer 9

The KEY to solving algebra problems is to isolate the unknown variable by doing the exact opposite of what's being done to it right now.

With 56 / X = 7 / 9, we first need to rearrange things into a more "workable format" by cross multiplying. Doing this gives us 7X = 504.

Since we're multiplying X by 7, we'd do the opposite by dividing both sides by 7, which would gives us X = 72.

Answer 10

Proportion Problem

56/x = 7/9

Multiply the Means and the extremes

7x = Means
56 X 9 = Extremes

7x = 504

7x/7 = 504/7

divide 7 from both sides

x = 72

The andwer is x = 72

The solution set is {72}
