Question

if the product oftwo rational numbers is 2 and one of them is 1/7, find the other number ​

Answer 1

Here,

• Product of two rational number = 2
• One of the multiplicand = $\sf \frac{1}{7}$

To find :- Another unknown multiplicand

$\huge \mathbb{\overline{ \: \: \: SOLUTION: \: \: }}$

We have,

$\: = > \rm{ \: \: 2 \: = \: \frac{1}{7} \times (unknown \: \: multiplier)} \\ \\ \rm \: = > \: \: 2 \: = \: \frac{unknown \: \: multiplier}{7} \\ \\ \: \boxed{ \textbf{ \: By multiplying 7 to both sides } \: } \\ \\ \rm \: = > \: 2 \times 7 = \: \frac{unknown \: \: multiplier}{ \cancel{7}} \times \cancel7 \\ \\ \rm \: = > unknown \: \: multiplier \: = \underline{ \: \red{14} \: }$

Hence,

• It is found that the unknown multiplicand is 14 which when multiplied with $\sf \frac{1}{7}$, equals 2.
