Question

a) 1/5
b) 1/3
c) 2/5
d) 3/5

Answer 1

Kalani had 3/5 of a pan of brownies and sent 1/3 of what she had to Mrs. Banner's house. After multiplying the fractions (3/5) × (1/3) and simplifying, we find that she sent 1/5 of the whole pan of brownies.

Step-by-step explanation:

Kalani had 3/5 of a pan of brownies. To find out what fraction of the whole pan she sent to Mrs. Banner's house, we need to calculate one-third of 3/5. Here's the calculation:

• First, write the problem as a multiplication of fractions: (3/5) × (1/3).
• Then, multiply the numerators together: 3 × 1 = 3.
• Multiply the denominators together: 5 × 3 = 15.
• Put the new numerator over the new denominator to get the fraction: 3/15.
• Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3. This gives us 1/5.

Therefore, Kalani sent 1/5 of the whole pan of brownies to Mrs. Banner's house, which corresponds to choice a).
