In this item, we are to supply for the missing term on one side of the equation. The left side is given to be composed of 62.834 x 0.45. The right hand side is given to be composed of 314170 along with a missing entity.
Translating the given to mathematical expression and letting A be the unknown,
62.834 x 0.45 = 314170 A
To determine the value of A, divide both sides of the equation by 314170.
(314170A)/(314170) = (62.834 x 0.45) / 314170
A = 0.00009
The missing value is 0.00009 or 9.0 x 10^-5.
