Question

please answer me step by step my question​

Answer 1

Answer:

2/5

Step-by-step explanation:

Let that missing number be x

We can write 8^-1 as 1/8 and 20^-1 as 1/20

Hence from question

(1/8) × (x) = (1/20)

x = 1 × 8

20 1

x = 2

5

Hence we need to multiply 2/5 in (8)^-1 to get (20)^-1
