Question

Mrs. Duggin walked every day for seven days. If she walked 9/10 of a mile each day for seven days, how many total miles did she walk? In repeated addition

Answer 1

Mrs. Duggin walked a total of
`(63)/(10) \ miles.`.

Explanation:

Given:

Number of miles walked on each day =
`(9)/(10) \ mile`

Number of days she walked = 7

We need to find the Total miles she walked using repeated addition method.

Solution:

Now we know that Repeated Addition means adding each group together and it is also known as Multiplication.

So we can Find Total miles she walked by adding Number of miles walked on each day with number of day times.

OR

we can Find Total miles she walked by Multiplying Number of miles walked on each day with number of days.

framing in equation form we get;

Total miles she walked =
`(9)/(10)+(9)/(10)+(9)/(10)+(9)/(10)+(9)/(10)+(9)/(10)+(9)/(10)= (9+9+9+9+9+9+9)/(10) = (63)/(10)\ miles`

OR

Total miles she walked =
`(9)/(10)*7= (63)/(10) \ miles.`

Hence Mrs. Duggin walked a total of
`(63)/(10) \ miles.`.
