Question

Which of the following represents the sum of
numerator and denominator in the simplified
expression of (3.23 +4.75)?
​

Answer 1

Answer:

889

Step-by-step explanation:

The sum of the two numbers= 7.89

789÷100

The numbers 789 and 100 don't have any common factors apart from 1 so it is the simplest form

Sum of numerator and denominator=789+100= 889

Answer 2

Answer:

879/110

989

Step-by-step explanation:

simplified  expression of (3.23 +4.75)

bar on 3 and bar on 75

x = 3.2333333

10x = 32.33333333

100x = 323.333333

100x - 10x = 323.3333333 - 32.333333

=> 90x = 323 - 32

=>x = 291/90

y = 4.75757575

100y = 475.757575

100y - y = 475.757575 - 4.75757575

=> 99y = 471

=> y = 471/99

291/90  + 471/99

= (291 * 11  + 471*10)/990

= (3201 + 4710)/990

= 7911/990

= 879/110

879 + 110  = 989
