Jamie has earned $80 +75 +145 +250 +80 = $630 so far this week. He needs to earn an additional $875 -630 = $245 to pay his bills.

If Jamie only has one last task, he must earn $245 on that task to pay his bills this week.

On Monday Carlos ran 1/8 of a mile on Wednesday he ran 5/6 of a mile Carlos ran 3/8 of a mile on Friday Which day did Carlos run

pishuonlain [190]

1/8 5/6 3/8
Make sure that in order to compare and rank them from least to greatest, you ned to first see that the denominator is the same.

1/8=3/24 5/6=20/24 3/8=9/24
1/8<3/8<5/6

Therefore, 5/6 is the greatest and also the farthest that Carlos ran.
