How are polynomials like other number systems such as whole numbers and integers?
Agata [3.3K]
You can add, subtract, and multiply them. These three operations obey the rules for integers. There's a polynomial division algorithm that fills formally the same role as the usual division algorithm for integers. Polynomials added to, subtracted from, or multiplied by other polynomials yield only polynomials. Likewise, integers added to, subtracted from, or multiplied by other integers yield only integers.

If a girl read 3/8 of a chapter book and another girl read 3/6 of a chapter book which girl read more pages
fredd [130]

Answer:

The girl which read 3/6 of a chapter book read more pages than the other girl.

Step-by-step explanation:

We need to compare between \frac{3}{8} \ and \ \frac{3}{6}

so, the denominator of both fractions should be the same number

Factor of 6 = 1 * 2 *          * 3

Factor of 8 = 1 * 2 * 2 * 2

-------------------------------------------

The common denominator  = 1 * 2 * 2 * 2 * 3 = 24

\frac{3}{8} = \frac{3*3}{3*8} =\frac{9}{24} \\\frac{3}{6} = \frac{4*3}{4*6} =\frac{12}{24}

Then compare between \frac{9}{24} \ and \frac{12}{24}  \\

So, the fraction of the great numerator will be the great fraction

\frac{12}{24}  > \frac{9}{24}

∴ \frac{3}{6} > \frac{3}{8}

==================================================

<u>Another solution:</u>

Convert both fractions to decimal:

3/8 = 0.375

3/6 = 0.5

0.5 > 0.375

===================================================

<u>Third Solution: </u>

As the numerators are equal

The fraction of least denominator is the great fraction

So, 3/6 > 3/8
