Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other.
<span>......................................... IF A + B = 0 , they are the additive inverse of each other.
</span>
<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>
<span>......................................... A.B = 1 , they are the multiplicative inverse of each other.
</span>
<span>Example of: </span>
<span>Additive inverses :................ 5 + ( - 5 ) = 0 </span>
<span>Multiplicative inverses...........5 x 1/5 = 1 </span>
Given :
C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.
To Find :
Two possible lengths for CD.
Solution :
Their are two cases :
1)
When D is in between C and E .
. . .
C D E
Here, CD = CE - DE
CD = 15.8 - 3.5 cm
CD = 12.3 cm
2)
When E is in between D and C.
. . .
D E C
Here, CD = CE + DE
CD = 15.8 + 3.5 cm
CD = 19.3 cm
Hence, this is the required solution.

Formula for surface area of a sphere of radius r is A = 4pi*r^2.
The same formula, for the case where the radius is 2.45 times greater, comes out to A = 4pi*[2.45r]^2.
Just find the ratio of
4pi*r^2 to 4pi*[2.45r]^2. It is 1/6.
