Answer : 4/7
Here it's given that Brad's family travelled 2/7 of the total distance to his uncle's house on Saturday . So if we assume the total distance to be 1 , then the remaining distance will be ,
[tex]\sf\longrightarrow 1 - \dfrac{2}{7}=\dfrac{7-2}{7}=\boxed{\dfrac{5}{7}}[/tex]
Again it's given that they travelled 4/5 of the remaining distance on Sunday . So , the distance travelled would be ,
[tex]\sf\longrightarrow \dfrac{4}{5}\times \dfrac{5}{7}=\boxed{\sf \dfrac{4}{7}} [/tex]
Therefore Brad's family travelled 4/7 of the total distance on Sunday .
