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
#24)evaluate [618] those are supposed to be bars instead of brackets
#25)find the reciprocal of (1/5)(15) once again I am lost on that one. I really appreciate your help.

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.

Submit your question at tutoteddy and get the answer. They charge only 99 cents for every three math problem. However, I think it's better to do your homework by your own and so you have to learn the subject properly. You can take help of the abovementioned site. Their qualified experts have Master's degree in Electrical Engineering, and a profound understanding of Math and Science
