Question

i need help with a question plz! Image in the comments

Answer 1

Set up a proportion \[\frac{ 10 }{ 8 } = \frac{ x }{ 4.8 }\]

Answer 2

so what do i do next do i cross multiply or?

Answer 3

You can do that or you can multiply out the denominators
I don't think cross multiplying is technically a "thing"

multiply both sides by 8 and 4.8
