What is the relationship between the quotient and the dividend when dividing a whole number by a fraction?

• The quotient is larger than the dividend.

• The quotient is equal to the dividend.

• The quotient is smaller than the dividend.

Why is the quotient larger than the dividend when dividing a whole number by a fraction?

• Because the whole number is divided into fewer parts.

• Because the fraction is larger than the whole number.

• Because more parts are needed to make up the whole.

• Because the fraction is a multiple of the whole number.
