Answer:
6
Step-by-step explanation:
One recipe uses 1/4 cup of red onions.
They have 1 1/2 cups of red onions.
We need to divide 1 1/2 by 1/4.
First, we convert the mixed numeral into a fraction. Then, to divide by a fraction, we multiply by the reciprocal of the fraction.
[tex] 1 \dfrac{1}{2} \div \dfrac{1}{4} = [/tex]
[tex] = \dfrac{1 \times 2 + 1}{2} \div \dfrac{1}{4} [/tex]
[tex] = \dfrac{3}{2} \times \dfrac{4}{1} [/tex]
[tex] = \dfrac{12}{2} [/tex]
[tex] = 6 [/tex]
