Hernando and Rachel are factoring 2mp-6p+27-9m. Is either of them correct? Explain your reasoning,

vichka [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as Hernando and Rachel's solution are not provided. So, I will just solve the question directly.

Given

$2mp-6p+27-9m$

Required

Factor

$2mp-6p+27-9m$

Group into 2

$2mp-6p+27-9m = [2mp-6p]+[27-9m]$

Factor each group

$2mp-6p+27-9m = 2p[m-3]+9[3-m]$

Rewrite 3 - m as -(m-3)

So, we have:

$2mp-6p+27-9m = 2p[m-3]-9[m-3]$

Factor out m - 3

$2mp-6p+27-9m = [2p-9][m-3]$

Convert the decimal expansion 0.1777 into a rational number

Helen [10]

Answer:

The rational form of the given number 0.1777 = $\frac{1777}{10,000}$

Step-by-step explanation:

The rational number is expressed as a number on the form of $(\frac{p}{q} ) , q \neq 0$

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

$\implies 0.1777 = \frac{01,777} {10,000} = \frac{1777}{10,000}$

Hence, the rational form of the given number 0.1777 = $\frac{1777}{10,000}$
