7b + 12f =____(hex value), which is ____(decimal value)?

I do not know how to be effective this out.need assist.

7b + 12f = 1AA (base 16) = 426 (base 10) = 000110101010 (base 2).

7b (base 16) = 123 (base 10)

12f (base 16) = 303 (base 10)

in hexadecimal each place value belonging to the number is usually 16n exactly where n will go from 0 in order to (number_length)-1 starting from the right.This provide you with the decimal value of a hexadecimal amount.

In cases like this:

7b
EQUALS
b = 11*160 = 11
PLUS
SIX = 7*161 = 112
EQUALS
123

12f
EQUALS
f = 15*160 = 15
PLUS
2 = 2*161 = 32
PLUS
1 = 1*162 = 256
EQUALS
303

Thus,
7b + 12f
= 123 + 303
= 426 (decimal)

123 + 303 = 426
plus 426 (decimal) = 1AA (hexadecimal).
