1. in how many ways can you arrange five mathematics books,four science books,and three english books, on a shelf such as that books of the same subject are kept together.
<h3><em><u>For Mathematics=5</u></em></h3>
<h2 /><h2>--------------------------------------------------------------------------------</h2><h2> </h2><h3><em><u>For Science=4</u></em></h3>
P=n!}
P=4!
P=4×3×2×1
P=24
<h2> --------------------------------------------------------------------------------</h2>
<h3><em><u>For English=3</u></em></h3>
P=n!
P=3!
P=3×2×1
P=6
<h2> --------------------------------------------------------------------------------</h2>
Multiply all the permutations:
P=120×24×6
P=17,280
<h2>--------------------------------------------------------------------------------</h2>
There are <u>17,280</u> ways we can arrange in a shelf.

-8 × -4 = 32
21/32
<u><em>IMPORTANT: This number is not negative, because a negative times a negative is a positive.</em></u>
By the way, if you didn't know how to arrive at the fraction here's how.
First, Address input parameters & values.
Input parameters & values: The decimal number = 0.65625. Then, write it as a fraction
0.65625/1
Multiply by 100000 both the numerator & denominator
(0.65625 x 100000)/(1 x 100000) = 65625/100000
65.625% = 65.625/100 or 65625/100000
Find LCM (Least Common Multiple) for 65625 & 100000.
3125 is the LCM for 65625 & 100000
Divide by 3125
65625/100000 = (65625 / 3125) / (100000 / 3125)
= 21/32
