Jen, I will attempt to write the others out.
#3)ADD: 57 + (22) I got 79
#4)Subtract 2.3(8.8) I got 6.5
#7)perform indicated operation:
21  (9) I tried to underline

21  (21) I got 12 over o or undfined
#8)Multiply:(4){3/2} This one lost me
#9) place in ascending order:
 2/5, 1/6, 7/8, 5/9, 3/4
I got 5/9, 2/5, 1/6, 3/4,7/8
#10)Determine the maximum and minimum values of these numbers.
3, 36/7, 1, 2/3, 5/4, 5, 26/9
I got min. 5 1/7 max. 3
Evaluate: [24]  [22]
I got 2
#12)find the reciprocal of 1/7(710)
I do not know how to do this one. Can you show me?
#13)Multiply: (1.3)(10)(4)
I got 52
#14)perform indicated operation:
116

77 I got 5/0 undefined
#15) subtract 7/9  [13/18] I was lost on this one
#16)multiply 13 * 7 I got 91
#17)divide: 15/3 that should be underlined i got 5
#18)subtract: 3614 i got 22
#19)divide: 12/4 igot 3
#20)multiply:(10)(6)(9) i got 540
#21)divide: 12/0 i got 0 or undefined
#22)add: 3/4 + 4/5 i got ig ot 31/20
#23)add: 4/5 + [3/4] i am lost on this one

3: correct, 4: the two negative signs make a positive so your answer is positive 6.5, 7: I do not understand the problem written that way, 8: (4)(3/2)= (4/1)(3/2)=12/2=6, 9: correct, 10: correct but keep it in the format that's given in the problem so you should list the min as 36/7, 11: Once again, you need to change your sign. Two negative signs together make a positive, so the problem becomes 24+22=2..will post the rest in a few

12. 1/7(710), always do parenthesis first, so 710=17, then do 1/7(17) and when you get that answer flip it for the reciprocal (the reciprocal of 2/3 is 3/2 and vice versa, the reciprocal of 4 is 1/4). 13, 14 correct, 15. 7/9(13/18)= 7/9+13/18, find the common denomintor which equals 18, 14/18+13/18=27/18=1 9/18= 1 1/2, 1621: correct, 22: 3/4 + 4/5= 15/20+16/20=31/20=1 11/20, 23, 25: based on the steps i've shown you for the ones like this, you should be able to do these by now, post if you would like them checked, 24: 618

Please note that everyone on here is a VOLUNTEER. If you have something due that day, don't expect that someone will always be available, especially when you post this many problems. Next time, try posting days in advance.
