what is the answer in 20 1/3 - 16 3/4

Sagot :

20 1/3-16 3/4
so first find the LCD of 3 and 4 which is 12 then convert to similar fractions
1/3= 4/12
3/4=9/12
so na convert mo na.
pagkatapos subtract na.
subtract mo muna ang mixed number.
20-16=4
tapos yung fraction
4/12-9/12
pero diba imposible so add mo yung 12 at 4
4+12=16
so 16/12-9/12=7/12
so 3 7/12
