Carly's family traveled 3/10 of the distance to her grandmother's house on Saturday. They traveled 3/7 of the remaining distance
polet [3.4K]

Answer:

3/10 of the total distance to her grandmother's house was traveled on Sunday

Step-by-step explanation:

Carly's family traveled distance of Saturday = \frac{3}{10}

Remaining distance =1-\frac{3}{10}=\frac{7}{10}

They traveled 3/7 of the remaining distance on Sunday.

So, Distance traveled on Sunday =\frac{3}{7}(\frac{7}{10})

Distance traveled on Sunday =\frac{3}{10}

Fraction of the total distance to her grandmother's house was traveled on Sunday =\frac{3}{10}

Hence 3/10 of the total distance to her grandmother's house was traveled on Sunday
