What is the product of 2.31 and 0.21?
Solution:
We need to find 2.31*0.21
Let us first find 231*21, then we would consider decimals
231*1=231
231*2=462
So, 231*21=231+4620=4851
So, we get 231*21=4851
But, we need to find, 2.31*0.21
There are two numbers after decimal in 2.31 (3 and 1). and, there are two numbers after decimal in 0.21(2 and 1)
So, In result of, 2.31*0.21 there must be four digits after decimal.
As, 231*21=4851
So, 2.31*0.21=0.4851 (four digits after decimal)
Answer:0.4851

Answer:
p = 20
Step-by-step explanation:
Collecting terms gives ...
(4/5 -3/5)p - 4 = 0
1/5p - 4 = 0
Multiplying by 5, we get ...
p - 20 = 0
Then, adding 20 gives the solution:
p = 20
