Question

Subtract the sum of -5/7 and 3/38 from the sum of 15/14 and 31/42​

Answer 1

Answer:

2.44

Step-by-step explanation:

[{(15/14)+(31/42)}-{(-5/7)+(3/38)}]

[{(45+31)/42}-{(-5*38+3*7)/38*7}]

=[{76/42}-{(-190+21)/266}]

=[{38/21}-{-169/266}]

=[{38/21}+{169/266}]

=[{38*266+169*21}/266*21]

=[{10108+3549}/5586]

=13657/5586

=2.44
