An algebra problems like 2+?=4.

0+4=4 1+3=4 2+2=4 -1+5=4
4 students can do 80 math problems in one hour. how many math problems can 8 students do in 3 hours?
Ok, SO if 4 students can do 80 math problems in one hour, each student can do 20 math problems an hour. This is because 80 math problems divided by 4 students/kids is 20, well 80 divided by or / by 4 is twenty. Ok, so each student can do twenty problems an hour, and twenty multiplied by 8 (because there are now eight students doing math problems) is 160. So, that is in one hour. So, then, to, find, how much they can do in 3 hours, multiply this by 3 because 160/h multiplied by 3 is x/3r. so now 160x3 is 480, so 8 students can do 480 math problems in 3 hours.Hope this helps!
What two simpler problems can you use to find 4 times 22?
22 * 2 =44 44 * 2 = 88 Partitioning 22 is not an option since that leads to 3 problems, not 2: 4 * 20 = 80 4 * 2 = 8 and 80 + 8 = 88
How is 4 over 12 divided into a decimal?
Think of fractions as division problems. 4 over 12 (4/12) is really just saying 4 divided by 12. Therefore, 4/12 = 4 divided by 12 = 0.3333 . . .
