Question

Please help with mathematics

Answer 1

Number 2 would be A.4/1/2
Number 1 would be C.
Number 3 would be .2/2
Number 4 would be D because you subtract.
Number 5 would be 22. x=22. 22 divided by 10 equals 2 1/5.
Hope this helps!:)

Answer 2

First question:-

Order from least to smallest.

9,3, 9 1/3, 37/4, 9.34

Now, let us get all the numbers in the same format.

37/4 = 9  1/4

9 1/4 = 9.25

9.34 

9.3 = 9.30

9 1/3 = 9.33

Now order them.

Final answer:   37/4, 9.3, 9 1/3, 9.34     DONE!

Second question:- 

6 1/2 + 5 1/5   =    6  5/10 + 5  2/10  =   11   7/10

11   7/10  +  2   4/5   =  11  7/10 +  2  8/10  =  13  15/10   =  14 1/2

14.5 =  n + 10 

Now solve for n

14.5 - 10 = n + 10
               -10

4.5 = n 

Final answer:    n = 4  1/2 


Third question:-

Reciprocity of 1 1/2

first, we make the mixed number an improper fraction.

1 1/2  =  1*2 = 2 + 1 = 3

3/2  the reciprocal of it is 2/3

Final answer: 2/3

Fourth question:- 

solve the proportion.

2 2/5 minutes to run 1.5 miles.

2.4/1.5 = 1/x

Cross multiply.      2.4*x = 1.5*1

2.4x = 1.5
-------------
   2.4

x = 2.4/1.5

Final answer:    x= 1  3/5

Fifth question:-

x/10 = 2 2/10        <--------- i made sure the denom's are the same!

22/10 = x/10 

x = 22

Final answer: x = 22

YES...WE HAVE OUR ANSWERS...AND THIS TOOK ME FOREVER. :D
