Question

The product of 2 rational no iz 10.one of them is -8 find the other

Answer 1

Given,

• Product of two rational number = 10
• One of the multiplicand = -8

• To find :- Other multiplicand

$\huge A \frak{N} \sf{S} \mathscr{W} \rm{E}R :$

We Have,

$\sf - 8 \times \text{( Unknown Multiplicand)} = 10 \\ \\ \: \: \boxed{ \: \textbf{Dividing both side by -8} \: \: } \\ \\ = > \frac{ \cancel{ - 8} \times\text{( Unknown Multiplicand)} }{ \cancel{ - 8}} = \frac{10}{ - 8} \\ \\ = > \text{Unknown Multiplicand} \: = \: \red - \frac{ \red{10}}{ \red8}$

Hence,

• THE REQUIRED UNKNOWN RATIONAL NUMBER (MULTIPLICAND) IS $\sf\red - \frac{ \red{10}}{ \red8}$.
