From unit Symbol Equals Result To unit Symbol
1 square centimeter cm2 , sq cm = 1.27 ∅ 1-centimeter circles ∅ 1 cm
Amount : 18 ∅ 1-millimeter circles (∅ 1 mm)
Equals : 0.14 square centimeters (cm2 , sq cm)
Fraction : 7/50 square centimeters (cm2 , sq cm)
Some bad people will tend to forge dollar bills and make fake bills, giving them to cashiers and asking for it to be split into a different amount of bills so they are given real cash and wont be caught or they will buy things, return them and be given back real money and get away with it.

I would go with 7 because its just water.
In this reaction the products have less potential energy than the reactants.
A scheme of a chemical reaction. The reactants are two molecules, one of which consists of A and B, and the other consists of C and D.
The products are two molecules, one of which consists of A and C, and the other consists of B and D.
The energy of molecules AB and CD is higher than the energy of molecules AC and BD.
In this reaction heat has been released to the environmen.
