Each but is 21/100 meters long. Write the fraction as a decimal then calculate how long all eight books are all together

1.68 Meters

Step-by-step explanation:

Hello I think I can help with this.

Well basically the way it is represented as a fraction is a portion of a whole like a percent :

For example : 21%

So basically we just need to turn this into a decimal and then add to find how long the books would be together.

How I would go about doing this is first looking at the 21/100 and remember that in decimals 1.00 is a whole just like the 100. So in this case the 100 in 21/100 would be 1.00.

So knowing this, we can take the 21 in 21/100 and say that 0.21/1.00 is equal to 21/100 because the 21 is representing how much of a meter the books are while 100 is the whole meter.

Now, we know we have eight books and each are .21 long. So we can do :

.21 x 8

=

1.68

While this is the answer we can write it in two ways. Either in fraction form like it started or in decimal form which I think is how they want you to write the answer.

For fraction :

168/100 Meters

We can simplify this :

1 68/100 Meters

EDIT :

We can simplify this even more :

Lets divide both sides by 2 :

34/50

AND we can do it again :

So divide by 2 on both sides :

17/25

And don't forget to add the 1 back into it :

1 17/25

And for the decimal form it is just what we found already :

1.68 Meters

I hope this helps!
