Answer:

Improper fraction: 13/10

Mixed number: 1 3/10

Decimal: 1.3

Step-by-step explanation:

Find common denominator: which is 30

Make each denominator equal 30, affecting the whole fraction:

6•2/15•2 + 3•3/10•3 + 3•6/5•6 =

12/30 + 9/30 + 18/30 = 39/30

Simplify: 39/30, divide both by 3: 13/10

And there is our answer!

Hope this helps, good luck! :D

ollegr [7]

Answer: There are 120 different ways we can arrange reindeer.

Step-by-step explanation:

Since we have given that

Number of reindeer = 5

Number of them fly their sleigh = 4

We need to find the number of different ways we can arrange their reindeer .

For this we will use "Permutation":

here, n = 5

r = 4

So, it becomes,

^nP_r=\frac{n!}{(n-r)!}\\\\So,\\\\^5P_4=\frac{5!}{(5-4)!}\\\\^5P_4=120

Hence, there are 120 different ways we can arrange reindeer.
