\bf \begin{array}{ccll} miles&hours\\ \cline{1-2}\\ \frac{1}{8}&\frac{1}{9}\\\\ x&1 \end{array}\implies \cfrac{~~\frac{1}{8}~~}{x}=\cfrac{~~\frac{1}{9}~~}{1}\implies \cfrac{~~\frac{1}{8}~~}{\frac{x}{1}}=\cfrac{1}{9}\implies \cfrac{1}{8x}=\cfrac{1}{9} \\\\\\ 9=8x\implies \cfrac{9}{8}=x\implies 1\frac{1}{8}=x

Using the fractions 2/3 and 3/4 describe how to give two fractions common denominators
Contact [7]
One way is to find the prime factorization for the denominators which are 3 and 4. The prime factorization of 3 would be 1 x 3 and 4 would be 2 x 2. Since we only use prime numbers to find the prime factorization we would have 2 x 2 x 3 = 12 which give us the the least common denominator for 2/3 and 3/4. Final answer is 12.

One month Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hours
LiRa [457]
<span>let number of hours of Isaac,Ruby and Svetlana worked be x,y and z respectively. so y= x+6 ( equation 1) note: Ruby (y) worked 6 hours more than Isaac (x) z = 4 x y ( equation 2) note : Svetlana (z) worked 4 times as many hours as Ruby (y) x+y+z= 126 ( equation 3) note: Together they (x,y,z) worked 126 hours. substitute eqn 1 to eqn 3 so x+y+z= 126 becomes y-6 + y+z-126 2y+z= 126+6 2y+z=132 (equation 4) the substitute eqn 2 in eqn 4 so 2y+z=132 becomes 2y+4y=132 6y=132 y=132/6= 22 so y=22 substitute y value in equation 1 so y= x+6 becomes x+6=22 and x= 22-6 = 16 and substitute x and y values in equation 3 so 16+22+z= 126 38+z= 126 z= 126 -38 = 88 So the number of hours Isaac worked (x) is 16 hours number of hours Ruby worked (y) is 22 hours number of hours Svetlana worked (z) is 88 hours</span>
