I need help! Please and thank you-
Ymorist [56]

Answer:

Well, I'm not really sure what to do, but if you just need the numbers to multiply to get the latter numbers in the question they are: 10/11 (for the first question) and 81/80 for the second.

Step-by-step explanation:

For Question #1: You just multiply 5/11 by two to get the number that 1/2 has to multiply to get 5/11. And 5/11 * 2 is 10/11. So I guess the answer is 10/11...

For Question #2: The common denominator for them both is 180, and 4/9 times 81/ 80 is what 80/180 (4/9) has to multiply by to get 81/180.

I used the equation 4/9x=9/20

Multiplied the 9 and then divided by 4 to get the answer, which was 81/80.

***I also noticed, that 1/2 is 1/22 away from 5/11, and 4/9 is 1/180 away from 9/20.

Hope this helps!

What are two rational numbers between -3/4 and -2/3​
Vadim26 [7]

The two rational numbers between -  \frac{3}{4}and -  \frac{2}{3}is -  \frac{32}{48},-  \frac{36}{48}

<h3>How to find the rational numbers between -3/4 and -2/3?</h3>

In the form of p/q, which can be any integer and where q is not equal to 0, is expressed as rational numbers. As a result, rational numbers also contain decimals, whole numbers, integers, and fractions of integers (terminating decimals and recurring decimals).

given that -3/4 and -2/3

now take L.C.M between these two rational numbers is 12.

now multiply -3/4 with 3 both numerator and denominator

-  \frac{3}{4}  \times  \frac{3}{3}  =   - \frac{ 9}{12}

again multiply -9/12 with 4 both numerator and denominator

-  \frac{9}{12}  \times  \frac{4}{4}  =  -  \frac{36}{48}

now multiply -2/3 with 4 both numerator and denominator

-  \frac{2}{3}  \times  \frac{4}{4}  =  -  \frac{8}{12}

again multiply -8/12 with 4 both numerator and denominator

-  \frac{8}{12}  \times  \frac{4}{4}  =  -  \frac{32}{48}

Hence the -36/48 and -32/48 are rational numbers between -3/4 and -2/3
