Question

The product of two rational number is-7 by 15 . if one of them is-7 find the other

Answer 1

Answer:

Missing  rational number is $\frac{98}{15}$ .

Step-by-step explanation:

To find : missing rational number :

Given : product of two rational number is -7 by 15 .One of them is -7 find the other .

Solution :

• As per given data we know that product of two rational number is -7 by 15 . One of them is -7 find the other .  
• Let , $x$ be the missing rational number .
• According to given condition we write as , $-7 +x = \frac{-7}{15}$
• Using transposition method we find the value of $x$ , by transposing constants at RHS and leaving variable at LHS .

      $-7 +x = \frac{-7}{15}\\\\x = \frac{-7}{15} + 7 \\\\x = \frac{-7 + 105}{15}\\\\x =\frac{98}{15}$
