Dividing by a fraction is the same as multiplicating by its inverse, I mean:
(a/b)/(c/d) = <span>(a/b)(d/c)
so for the fractions we have:
</span><span>7/9 divided by 8/15
= (7/9)/(8/15)
</span><span>= (7/9)(15/8)
</span>= 7*15/9*8
= 105/72
= 35/24

The importance of the omited variable by the means of that the "difference in means" test in unsuitable for determining the gender bias in setting wages.

kolbaska11 [484]
The answer is A. 42

Solution:
Let x= ones digit, y=tens digit

1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y

simplifying:
1st condition: 6x=3y
2nd condition: x=2
substituting x=2 to 6x=3y
<span>y=4</span>
