Hey There! I can help you by explaing how to solve it but you need to solve the answer yourself so you can learn :( . To find what fraction is x you will wanna cross multiplying and simplifying the equation to find x. As a example, 4/10 = x/15 solve for x. Since 60 = 60 is true, you can be sure that x = 6 is the correct answer. Hope this helps!
