Final answer:
To save all 147 babies from the Titanic, you will need 19 lifeboats. This problem is a division or fair share problem; you divide the total number of babies by the number each lifeboat can carry and round up.
Step-by-step explanation:
To determine how many lifeboats you will need to save the babies on the Titanic, you can use simple division. There are 147 babies in the nursery and each lifeboat can hold 8 babies (since each of the 8 women can hold one baby). So, you divide 147 babies by 8 babies per lifeboat.
147 ÷ 8 = 18.375 lifeboats
Since you cannot have a fraction of a lifeboat, you will need to round up to ensure each baby has a place. Therefore, you will need 19 lifeboats to save all 147 babies. This type of problem is considered a division or a fair share problem, where you are dividing a total number into equal groups and rounding up if there is a remainder.
