Which is bigger 2/5 or 4/9

Jlenok [28]

The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.

2/5 = 18/45
4/9 = 20/45

Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5

What's bigger 2/3 or 4/5

Eduardwww [97]

The best thing to do is either to find a common denominator or convert them to decimals.
I will find a common denominator.
A common denominator of 3 and 5 is 15.
You multiply the first fraction by 5
2*5= 10
This then becomes 10/15
You then multiply the second by 3.
4*3= 12
Therefore, this becomes 12/15
As the second of these fractions is larger, this means that 4/5 is larger.
The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8
Hope this helps :)

Answer:

<em>The difference quotient of f is 8. </em><em>Option C</em>

Explanation:

<u>Difference Quotient</u>

Given a function f(x), the difference quotient is defined as

$\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0$

The function provided in the question is

$f(x)=8x+1$

Find f(x+h) by substituting x by x+h:

$f(x+h)=8(x+h)+1$

$f(x+h)=8x+8h+1$

Now compute:

$\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}$

Operating:

$\displaystyle d=\frac{8x+8h+1-8x-1}{h}$

Simplifying:

$\displaystyle d=\frac{8h}{h}$

d=8

A. Incorrect.

This choice is different from the answer.

B. Incorrect.

This choice is different from the answer.

C. Is correct

The difference quotient is 8 as explained above.

D. Incorrect.

This choice is different from the answer.
