Kyle painted 2/5 of his door red and 1/2 blue. how much of the door did kyle paint billie?

to add the fractions you have to find a common den. so for example, 10. 2/5 becomes 4/10, and 1/2 becomes 5/10. he painted 9/10 of the door red and blue. not sure if that's what you're asking but here to help more if needed

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
