5× 1/2 = ? a) more than 5 because you are multiplying by a whole number b) 5/10 because you multiply the numerator and denominator by 5 c) less than 5 because you are multiplying by a number that is more than 1 d) less than 5 because you are multiplying by a number that is less than 1

Angles r and s are complementary. the measure of angle r is 31 degrees. which equation can be used to find angle s?

In an improper fraction, is the numerator equal to, less than, or greater than the denominator
