Question

$\frac{1}{k} - \frac{1}{4} = 5$
solve the above by using change of subject​

Answer 1

Answer:

4/21

Step-by-step explanation:

Given:

• 1/k - 1/4 = 5

Subject is k, so the following steps are to solve it for k:

• 1/k = 5+ 1/4       ⇒ adding 1/4 to both sides
• 1/k = 21/4          ⇒ simplifying the fraction on right side
• k = 4/21             ⇒ inverting both sides to get answer

Answer is 4/21

Answer 2
