Question

If blank`div 10 =1`, what is blank`xx8/10`?

Answer 1

'blank' = `10" and "` blank`*8/10=8`

[Assuming that 'blank' is a variable and we are asked find
blank`*8/10`]

Explanation:

If "blank' is the unknown variable in this question, let blank `=x`

Then: `x/10=1 = 10/10 rarr x=10`

Hence: `x*8/10 = 10*8/10 = 8`
