Answer 1

A foreign exchange student wants to ship is option D, which is 67 kilograms.

Step-by-step explanation:

To find the total mass of all three packages, we need to add the masses of package A, B, and C together.

First, convert the mixed numbers to improper fractions:

Package A: 22 3/8 kg = 22 + 3/8 = 22 + 3/8 = 22 + 0.375 = 22.375 kg

Package B: 26 1/4 kg = 26 + 1/4 = 26 + 0.25 = 26.25 kg

Package C: 18 5/8 kg = 18 + 5/8 = 18 + 0.625 = 18.625 kg

Now, add the masses together: Total mass = 22.375 kg + 26.25 kg + 18.625 kg Total mass = 67.25 kg

Rounding to the nearest whole number, the total mass of all three packages is approximately 67 kilograms.

The correct answer is option D, which is 67 kilograms.
