Answer:

Negative numbers are most important especially in the field of physics and chemistry. They help us in real life geometry and in almost everything. The discovery of the number system has changed the human civilization to such a great extent, that, without it, we can't even think of architectures and the nature's law(by calculus).

Dominantly, zero is the most ever used number and is very important to express anything.

Without it, you couldn't have the digital world (simply, no computers, no phones, no machines and no A.I.).

As we all know, Dr. Aryabhatta, the legendary guy, who made the no. '0', holds the credits!

I hope it will be useful.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed o

kvv77 [185]

The left-handed students
12% are left handed, percent means per hundred. Change percent into per 100.
12% = $\dfrac{12}{100}$

Then simplify the fraction by dividing the numerator and denominator by 4
$\dfrac{12}{100}$
= $\dfrac{12:4}{100:4}$
= $\dfrac{3}{25}$
This is the fraction showing the proportion of the left-handed students

The right-handed students
Determine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 - $\dfrac{3}{25}$

Equalize the denominator to 25
$\dfrac{25}{25} - \dfrac{3}{25}$

Simplify
$\dfrac{21}{25}$
This is the proportion of the right-handed students

<span>Are there more right-handed or left-handed students?
There are more right-handed students than the left-handed students, because 21/25 is more than 3/25</span>
