To determine whether each sum is closer to 300 or 400, you can find the difference between the sum and both 300 and 400. The smaller difference will indicate which number the sum is closer to.
Here are the calculations for each expression:
1. 206 + 142:
Difference from 300 = 300 - (206 + 142) = 48
Difference from 400 = (206 + 142) - 400 = -52
The difference from 300 is smaller, so this sum is closer to 300.
2. 198 + 149:
Difference from 300 = 300 - (198 + 149) = -47
Difference from 400 = (198 + 149) - 400 = -53
The difference from 300 is smaller, so this sum is closer to 300.
3. 94 + 258:
Difference from 300 = 300 - (94 + 258) = -52
Difference from 400 = (94 + 258) - 400 = -48
The difference from 400 is smaller, so this sum is closer to 400.
4. 246 + 132:
Difference from 300 = 300 - (246 + 132) = -78
Difference from 400 = (246 + 132) - 400 = -22
The difference from 400 is smaller, so this sum is closer to 400.
Based on the calculations, the sums are closer to the following numbers:
1. 206 + 142: Closer to 300
2. 198 + 149: Closer to 300
3. 94 + 258: Closer to 400
4. 246 + 132: Closer to 400
