Required number = 1/2 (2/7 + 3/4)
= 1/2 ((8 + 21)/28)
= {1/2 × 29/28)
= 29/56
Hence, 29/56 is a rational number lying halfway between 2/7 and 3/4.
(-3i+4) (3i+4)
(-3i*3i)+(-3i*4)+(3i*4)+(4*4)
-3i^2 - 12i + 12i + 16
Since i^2 = -1
we get:
9 - 12i + 12i + 16
=25
Therefore, the product of the complex numbers is 25.
Answer 0.6
(3/2)x(2/5)= (3/5) or 0.6
Answer:
Any whole number is over one...so if the whole number was 5 it would be 
bkuz the line in between the numerator and denominator is a dividing sign and 5 divided by 1 is 5
So you put the whole number whatever it is over 1 then multiply that by the fraction
Example:
6 x 
is the same as saying 
x which equals 
because 6 times 3 equals 18 and 4 times 1 equals 4
Now you need to simplify or divide...
So, is the same as 
or 
bkuz 4 goes into 18 4 and a half times
