What is one fifth of one and a half cups?

Answer 1

When working with mixed numbers it is usually easier to convert them to improper fractions, do the calculation and convert any resulting improper fraction back to a mixed number.

1/5 × 1 1/2 cups = 1/5 × (1×2+1)/2 cups

= 1/5 × 3/2 cups

= (1×3)/(5×2) cups

= 3/10 cup

Answer 2

Convert 1 1/2 c to an improper fraction by multiplying the denominator by the whole number and adding the numerator. Place the results over the denominator.

1 1/2 c = (2 x 1 + 1)/2 = 3/2 c

Now multiply by 1/5 by 3/2 c.

1/5 x 3/2 = 3/10 c

Answer 3

It is 0.3 cups.
