To solve this task, we need to subtract the numbers in each star and then determine if the result is odd or even.
Step 1: Subtract the numbers in each star.
Step 2: Check if the result is odd or even.
- If the result is odd, the star should be colored blue.
- If the result is even, the star should be colored red.
Let's go through each star:
1.
456 - 384
- Calculation: 456 - 384 = 72
- 72 is even, so color the star red.
2.
383 - 237
- Calculation: 383 - 237 = 146
- 146 is even, so color the star red.
3.
795 - 337
- Calculation: 795 - 337 = 458
- 458 is even, so color the star red.
4.
451 - 389
- Calculation: 451 - 389 = 62
- 62 is even, so color the star red.
5.
649 - 362
- Calculation: 649 - 362 = 287
- 287 is odd, so color the star blue.
6.
586 - 177
- Calculation: 586 - 177 = 409
- 409 is odd, so color the star blue.
7.
375 - 246
- Calculation: 375 - 246 = 129
- 129 is odd, so color the star blue.
8.
426 - 286
- Calculation: 426 - 286 = 140
- 140 is even, so color the star red.
9.
567 - 295
- Calculation: 567 - 295 = 272
- 272 is even, so color the star red.
10.
674 - 377
- Calculation: 674 - 377 = 297
- 297 is odd, so color the star blue.
Final Answer:
- Stars to color red: 456 - 384, 383 - 237, 795 - 337, 451 - 389, 426 - 286, 567 - 295
- Stars to color blue: 649 - 362, 586 - 177, 375 - 246, 674 - 377
