Sangeetha prepared a cake of which 3/4was eaten by her brother 1/7 by her sister and rest by her . What part of cake did she have

Answer 1

Answer: 3/28

Step-by-step explanation: first you must find a common denominator for both fractions=28

3/4 = 21/28 , 1/7 = 4/28

now you add both no. together: 21/28 + 4/28 = 25/28

after this you subtract the no. you got from the whole no. : 28/28 - 25/28 = 3/28

you can leave your answer like this unless it can be simplified.
