Which number is between 0.6 7/9
irakobra [83]
First we make the fractions homonym ( they must have the same denomitator)

0.6 = 6 / 10                                                  7/9

6/10 = 6 * 9 / 10 * 9 = 54 / 90                        7/9 = 7 * 10 / 9 * 10 = 70 / 90

The numbers which are between these numbers are ;

55 / 90 , 56 / 90 , 57 / 90 , 58 / 90 , 59 / 90, 60 / 90 , 61 / 90 , 62 / 90 , 63 / 90 , 64 / 90, 67 / 90 , 68 / 90 , 69 / 90

62 / 90 = 62 / 2 / 90 /2 =  31 / 45 

So the right answer is B.

Hope that helps :)

Help with 12!! ASAP will gove brainliest!! How to find the surface area!!
Shkiper50 [21]

Answer: 659 13/18 yd^2 or 659.7yd^2                ^ =squared

Step-by-step explanation:

This is the answer because you have 6 sides of this prism. That means 3 sides are parallel to the sides across from them. So, 12 1/2 yd by 8 1/3 yd is 104 1/6, then multiply by 2. That equals 208 1/3. Then, 10 5/6 yd by 8 1/3 yd is 90 5/18. then times by 2. That equals 180 5/9. Next, 10 5/6yd by 12 1/2 is 135 and 5/12. then times by 2 and that is 270 5/6yd.

add 208 1/3 + 180 5/9 + 270 5/6

659 13/18 yd^2
