What you are doing is called cross multiplication. You have to multiply the top of the first fraction by the bottom of the second fraction. 1 x 378, which equals 378. Then you multiply the bottom of the first fraction by the top of the second fraction. 250 x X. 250x=378. You then have to solve for x or divide 378 by 250. The answer to 378 / 250 = 1.512. But the instructions want you to round to the nearest tenth and that is the first decimal place. Your answer is 1.5.
I think the appropriate answer is, the integers, polynomials and whole numbers since of them are closed under multiplication.
Integers are whole numbers, while polynomials are expressions with more than two algebraic terms.
