Whats 6 and 2/3 -4 and 1/6.

1 answer:

4 0

2.5, because 6 2/3 - 4 1/6....

First, find the most common denominator! Which is 6.
Multiply the bottom term to 2 times. (To get 6.) Now do the same for the top! So 6 4/6 - 4 1/6

Second, you subtract!
2 3/6

Third, if your teacher has ever taught you this or not....
If she did: Simply 2 3/6 into 2 1/2!

Finally,
2 1/2 can be 2.5, 2 3/6, or just 2 1/2!

the length of a rectangle is 5cm longer than twice the length of the width. if the perimeter of the rectangle is 88, what Is the

o-na [289]

Width=x
length=2x+5
perimeter of a rectangle=2(length)+2(width)
We can suggest this equation:
88=2(2x+5)+2x

88=4x+10+2x
6x=88-10
6x=78
x=78/6
x=13

width=x=13
length=2x+5=2(13)+5=26+5=31

Answer: the width would be 13 cm.
