help with several mathe problems?

Question

The answers to the left are what I think is correct

1. Write in decimal form 94 17/1,000 - 94.17000

6
2. Multiply. - 0.092 x 10 - 0.552 note the 6 is over the 10

3. Find two factors of 120 with a difference of 2. - 10

4. Determine whether the pair of fractions is proportional:
2/5 - 6/15 - I think so just not sure

5.Find the reciprocal of (- 1/5) (15)

Answer 1

1.94.017

2.{6*(-0.092)}/10
=--0.0552

3.12 and 10

4.yes they are

5.it is -5

Answer 2

1. Write in decimal form 94 17/1,000 - 94.17000
s/b 94.017

6
2. Multiply. - 0.092 x 10 - 0.552 note the 6 is over the 10
-0.092*6/10 = 0.0552

3. Find two factors of 120 with a difference of 2. - 10
120 = 10*12

4. Determine whether the pair of fractions is proportional:
2/5 - 6/15 - I think so just not sure
(2/5)(3/3) = (2*3)/(5*3) = 6/15

5.Find the reciprocal of (- 1/5) (15)
1/(-1/5) = 1*5/(5*(-1/5) = 5/-1
(5/-1)(-1/-1) = -5/1 = -5

Answer 3

Can only help with #4 it is proportional

Answer 4

1) 94.017

That's all I could figure out. I need to go back to school.
