Answer :
We know that 30 students have 17 dogs. If we want to know how many dogs will have 10 times more students (300) we can miltiply 17 times 10 as well to get the answer.
17*10=170 - its predicted value
17*10=170 - its predicted value
so 17 out of 30 or 17/30
so we want to find the equivilent of 17/30 with the bottom number 300 so
we know that 1/2=4/8 because 1/2 times 4/4 ( or 1) =4/8 soo
we notice that 300 is 10 times of 30 so
17/30 times 10/10=170/300 so
170 student have a dog
