yesterday I read 1/6 of a book, and today I read another 1/4 of it . what fraction of the book did I read in two days

Sagot :

  1/6=72/12
+1/4=48/12

= 72/12 + 48/12 = 120/12
                             = 10/12
          answer      =  5/12
2/12+3/12=5/12 first is find the LCD of denominator is 12 divide it to denominator and multiply it the numerator to denominator after add the numerator and copy the denominator.
