dgud

wat are the poperties of math and what do they all mean?????????

i need help in my homework

I haven't used the expression "front end" estimation but I would simply round 12,249 to 12,000 and subtract 7,000 to obtain about 5,000. The actual number is 5,374.

how do you do equiaelent fractions without fraction bars?

You can just multiply the top and bottom # my the same # to get an equiveilent fraction. EG: 1/2

1 * 6=6

2 * 6=12

You new fraction is 6/12! hope this helps!
