18 · 486 - 468 = 18.
486 · 486 > 468. The rest are all smaller than 468.
512 · 512 has 5 hundreds and 398 has 3 hundreds. 5 is more than 3.
True · Both numbers start with 6 hundreds, so the tens digit (1 vs 2) decides which is bigger.
615 · The smaller is 605, and 605 + 10 = 615.
350 · Compare the hundreds: 5, 3, and 5. 350 has only 3 hundreds, so it is the smallest.
209, 219, 229, 239 · 209 < 219 < 229 < 239 rises every step. The rest jump up and down.
True · Lena is right: 502 < 512 < 521.
No, she should have compared the tens digit first · Both numbers have 4 hundreds, so compare the tens next: 2 is less than 3, so 429 is smaller. The ones digit never mattered.
908 · 908 is the largest: 9 hundreds with 0 tens beats 899, 890 and 889.
