5/9
They can both be divided by 5 to make the originally number smaller and easier to work with.
Hope this helps! :)

All you have to do is notice that 5 is a common factor of both 25 and 45. Divide both numbers by 5 and you get 5/9.

$\frac{1}{6} + \frac{1}{12}$

We know that:

$\frac{a}{b} + \frac{c}{d} = \frac{a.d + b.c}{bd}$

So,

$\frac{1}{6} + \frac{1}{12} = \frac{1.12+6.1}{6.12}$

$\frac{12+6}{72}$

$\frac{18}{72}$

$\frac{9}{36}$

$\frac{3}{12}$

$\frac{1}{4}$

Perimeter of a rectangle is 15x+17y if the length is 7/2x+7y then find the width of the rectangle

bogdanovich [222]

The perimeter of a rectangle is given by the formula,

$P=2l+2w$

We substitute,

$P=15x+17y$

and

$l=\frac{7}{2}x+7y$

into the above formula to obtain the expression,

$15x+17y=2(\frac{7}{2}x+7y)+2w$

$15x+17y=7x+14y+2w$

We now group the x and y terms on the Left Hand Side of the equation to get.

$15x-7x+17y-14y=2w$

$8x+7y=2w$

We now divide through by 2 to get,

$4x+\frac{7}{2}y=w$

Therefore the width of the rectangle is

$4x+\frac{7}{2}y$
