These questions are a bit hard and I would like help from anyone really = 2.9+6 2/5, 16 3/4 + 8.25, 3 1/2 - 2/5, and 3 1/4 + 3/25 . If you could help I'd appreciate it very much < 3

1)9 1/10 or 9.1, 2)25, 3)3 9/10 or 3.9, and 4)3 37/100 or 3.37

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.
