Question

product of two no is -21/22. if one of the no is 9/11 find the other
no wrong thing if u do i will report u
plz give me asnwer fast​

Answer 1

Answer :-

• The other number is -7/6.

To find :-

• The other number.

Solution :-

• It is given that the product of two numbers is -21/22 and one of the numbers is 9/11. We have to find the other number.

Let :-

• The other number be "x".

Then,

• The product of x and 9/11 will be -21/22.

Therefore,

$\longmapsto\sf x \times \dfrac{9}{11} = \dfrac{-21}{\:\:\:22}$

$\longmapsto\sf x = \dfrac{-21}{\:\:\:22} \div \dfrac{9}{11}$

$\longmapsto\sf x = \dfrac{-21}{\:\:\:22} \times \dfrac{11}{9}$

$\longmapsto\sf x = \dfrac{\:\:\not\!\!\!\!\!\!\!-21}{\:\not\!\!\!\!122} \times \dfrac{\:\not\:\!\!\!11}{\!\not9}$

$\longmapsto\sf x = \dfrac{-7}{\:\:\:2} \times \dfrac{1}{3}$

$\longmapsto\underline{\boxed{\sf x = \dfrac{-7}{\:\:\:6}}}$

• Hence, the other number is -7/6.

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

Verification :-

• To check our answer, let's multiply both the numbers and see whether their product is -21/22.

Here,

• First number is 9/11.
• Second number is -7/6.

Therefore, their product is :-

$\longrightarrow\tt \dfrac{9}{11} \times \dfrac{-7}{\:\:\:6}$

$\longrightarrow\tt \dfrac{-63}{\:\:\:66}$

$\longrightarrow\tt \dfrac{-21}{\:\:\:22}$

We observe that :-

• The product of 9/11 and -7/6 is -21/22.

Hence verified!
