For the Christmas dance, they will need 51 songs.
What is average?
A number that is calculated by adding quantities together and then dividing the total by the number of quantities.
Given that, For the Christmas dance, the dance committee needs three hours of music. Each song is an average of 3.5 minutes.
Converting 3 hours into minutes,
1 hour = 60 minutes
3 hours = 60x3 = 180 minutes
Since, on song is of 3.5 minutes,
So, number of songs that will be played in 3 hours,
= 180/3.5
= 51.42
≈ 51
Hence, the party will have to play 51 songs.

there are three hours so
60*3=180
how many times will 3.5 go into 180 so
180/3.5=51.43 or rounded up you get 52 songs (if they're good, they'll play 52 average songs and one half legnth songs)
so they will need 52 songs

Answer: Hello there!
As we know, each 1/2 mile there is a red ribbon, each 1/8 mile there is a green ribbon, and each 1/4 mile there is a blue ribbon.
We want to know which color of ribbons is in the 3/4 mile marker.
then we need to see if 3/4 is a multiple of some of the previous numbers.
Start with the red ribbons, we need to see the quotient between 3/4 and 1/2, if the result is a whole number, then 3/4 is a multiple of 1/2
this is q = (3/4)/(1/2) = (3/4)*2 = 6/4
here we haven't a whole number, then there is no red ribbon at the 3/4 mile marker.
now with the green ones:
(3/4)/(1/8) = (3/4)*8 = 24/4 = 6
there we have a whole number, this means that at the 3/4 mile marker, we will see the sixth green ribbon, then we have a green ribbon in this marker.
now with the blue:
(3/4)/(1/4) = (3/4)*4 = 3
At the 3/4 mile marker, we will see the third blue ribbon, then there is a blue ribbon in this marker.
Then we know that in the 3/4 mile marker, there are a green and a blue ribbon.
