Convert: \[ 1 \mathrm{~km} 111 \mathrm{~m}=\square \mathrm{m} \]

To convert kilometers and meters into meters, you start with the fact that 1 kilometer is equal to 1000 meters. Therefore, \(1 \mathrm{~km} = 1000 \mathrm{~m}\). Now, add the additional 111 meters: \[ 1 \mathrm{~km} + 111 \mathrm{~m} = 1000 \mathrm{~m} + 111 \mathrm{~m} = 1111 \mathrm{~m} \] So, \(1 \mathrm{~km} 111 \mathrm{~m} = 1111 \mathrm{~m}\). To put it simply, you can think of it as stacking blocks: 1000 blocks (for the kilometer) plus 111 more blocks (for the meters) gives you a total of 1111 blocks (meters). Easy peasy!
