To solve this problem, we need to
round each mixed number to the nearest whole number.
🔢 Rule for Rounding Mixed Numbers:
- Look at the
fractional part (the fraction after the whole number).
- If the fraction is
less than 1/2, round
down to the smaller whole number.
- If the fraction is
greater than or equal to 1/2, round
up to the next whole number.

💡
Tip: You can also think of it as comparing the fraction to 1/2 — if the numerator is more than half the denominator, round up. For example, in 5/9: half of 9 is 4.5 → 5 > 4.5 → round up. Same logic applies!
