Question

Brad's family traveled

Answer 1

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 ,

$\sf\longrightarrow 1 - \dfrac{2}{7}=\dfrac{7-2}{7}=\boxed{\dfrac{5}{7}}$

Again it's given that they travelled 4/5 of the remaining distance on Sunday . So , the distance travelled would be ,

$\sf\longrightarrow \dfrac{4}{5}\times \dfrac{5}{7}=\boxed{\sf \dfrac{4}{7}}$

Therefore Brad's family travelled 4/7 of the total distance on Sunday .

Answer 2

Distance travelled by them on Saturday = 2/7

Distance travelled by them on Sunday = 4/5

Let total distance be 1, So according to that

$\sf1 - \frac{2}{7}$

$\sf \frac{7 - 2}{7}$

$\sf \frac{5}{7}$

Now, Multiply the distance travelled by them on Saturday by the fraction of distance they travelled on Sunday.

$\sf \frac{\cancel5}{7} \times \frac{4}{\cancel5}$

$\sf \frac{1}{7} \times \frac{4}{1}$

$\sf \frac{4}{7}$

Thus, Brad's family travelled 4/7 of the distance on Sunday...~
