Hint 2 of 2
From 7 weeks 2 days, count the days needed to reach exactly 8 weeks.
Show solution
Approach: count days to the next whole week
- Going from 7 weeks up to 8 weeks is one more full week, which is 7 days.
- The kangaroo has already lived 2 of those days.
- So 7 − 2 = 5 more days until it is 8 weeks old.
