A: 8*9= 72
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7
C: 7(5+9)
Great job for figuring it out on your own
<span>There is not friction force. Friction force refers to the an object moving and the friction not allowing it to move, however in this case the wall is what is keeping it from moving not friction.</span>
I think this is one of the reducing fractions problem:
If we look at option A.{1/4} {1/5} {1/6} {1/7} {1/8}.
Here, the reduced form of all the fractions is not equal to 1/4
If we look at option B. <span>1/4,2/4,3/4,4/4,5/4.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
if we look at option C. </span><span>1/4,2/8,3/12,4/16,5/20.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
If we look at option D.</span>1/4,2/8,4/16,6/24,8/32.
Here, the reduced form of all the fractions is equal to 1/4
i.e.
1/4 = 1/4
2/8 = 1/4
4/14 = 1/4
6/24 = 1/4
5/20 = 1/4
So, the correct answer is D.
