Aurelia wants to enlarge a 4 inch by 6 inch photo so that it has a width of 15 inches use a ratio table to determine the new length of the photo.

Ok, this is a ratio problem; the ratio of the length to width is constant (and therefore equal):           4 /6 = 15 / x Now, with a ratio, we may do any allowable algebra operation:  cross-multiply, invert both sides, multiply or divide both sides by the same amount, etc. Let's cross-multiply:        4x = (15)(6)          x  = 90/4          x = 22.5 in. 

The answer will be 22.5 inches.

Hope this helped, and please mark brainliest! :)
