Question #377c3

Answer 1

`g= 10 or g=1/10` depending on what is meant in the question,

Explanation:

It is not clear whether the question means:
`4 = (2g)/5 " "or" "4= 2/(5g)`

Let's consider both.

`4 = (2g)/5" "larr xx 5/2` on both sides

`4 xx5/2 = (2g)/5 xx 5/2`

`10 =g`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Or

`4= 2/(5g)" "larr`invert both sides

`1/4 = (5g)/2" "larr xx 2/5` on both sides

`1/4 xx2/5 = (5g)/2 xx 2/5`

`1/10 = g`
