2/3 is the same as 10/15 if you multiply top and bottom by 5

2*5 = 10

3*5 = 15

Or you can go backwards to divide each piece of 10/15 by 5 and you'll reduce that fraction to 2/3.

Bond [772]

Answer:

2.4 hr. = time working together

Step-by-step explanation:

Let x = time working together

x/6 = work done by Martin

x/4 = work done by Victor

Martin's part + Victor's part = 1 jog done

x/6 + x/4 = 1  Multiply thru by 12

2x + 3x = 12

5x = 12

x = 2.4 hr.

Does a polygon usually have more sides or <br> more angles
xxTIMURxx [149]

I've seen this question on Brainly before, and I always shake my head.

Please think about this for a few seconds.  Maybe even make some
scribbles on a piece of paper.

-- A triangle has 3 sides and 3 angles.

-- A square, rectangle, rhombus or parallelogram has 4 sides and 4 angles.

-- Draw anything with 5 sides.  It doesn't have to be pretty, and they don't
all have to be the same length or anything special.  Just draw any shape
with 5 sides.  Count the angles, and you'll find that there are five of them.

By now you should be starting to get the creepy hunch that maybe a
polygon always has the SAME number of sides and angles.  I hope so. 
That's the correct creepy hunch. 

You can get all kinds of hunches, and even work most of them out,
just by using your thinker for a while.
