Final answer:
Shopmart and Savemart bought the same amount of apples.
Step-by-step explanation:
To determine if Shopmart and Savemart bought the same amount of apples, we need to compare the fractions representing the number of crates they bought. Shopmart bought 9 and a half crates, which can be written as 9 + 1/2 or 18/2 + 1/2. Savemart bought 18/2 crates.
We can see that 9 + 1/2 is equal to 18/2 + 1/2, which means that both Shopmart and Savemart bought the same amount of apples.
Therefore, based on the fractions, we can conclude that Shopmart and Savemart bought the same amount of apples.
