Step-by-step explanation:
taking that blank as x
5/2 -x = 1/3
the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3
so the equation will become 5/2-1/3=x
solving the fraction then gives 13/6 or 2.17 as the value of x
Nanometers are a really small measurement, one billionth of a meter, I believe.
So nanometers is used to describe tiny stuff, like atoms of a water molecule, and waves of light.
