Answer:

Step-by-step explanation:
Step 1: Add the numbers.
20.25 can also be expressed as
, because
=
=
. So if we add
and 11, we would get 
Step 2: Solve

- Subtract the whole numbers

This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.

LCM

Therefore, the simplified expression to this is

Answer:
4378
Step-by-step explanation:
Its clearly given that each term is multiplied by 3
I.e- 2×3 = 6
6×3= 18
and so on....
so here the G.P series is a=2 and r=3
To find the 8th term ar^8-1
ar^7 = 2×3^7
= 2×2187
= 4378

It is symmetrical.
The first diagonal is all 1’s.
The second diagonal is the counting numbers.
Any number in the triangle is the sum of the two numbers directly above it.
Each row adds to a power of 2.
The product of given expression is 
<em><u>Solution:</u></em>
Given that we have to find the product and write it in lowest term
Given expression is:

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

Substituting these in above expression, we get

Cancel the common factors in numerator and denominator

In decimal form, we get

Thus the product of given expression is
