There were 30 cookies in a jar. Eileen divided the cookies into 12 equal shares. How many cookies were there in each share?
Sedbober [7]
The answer is 2.5 cookies also known as 2 and 1/2 Because 12 can go into 30, twice , which gives us 24 and 30-24= 6 so we put a decimal point to the right of 2 and we put a 0 and bring the zero down to make 60. 12 goes into 60, 5 times so the answer is 2 1/2 or 2.5

Pachacha [2.7K]
In the given question we can see that the information,Georgina ran a distance of 3/8 mile in 3 minutes is already provided.
So
In 3 minutes Georgina can run a distance of = 3/8 miles
Then In 1 minute Georgina can run a distance of = 3/(8 * 3) miles
                                                                               = 3/24 miles
                                                                               = 1/8 miles.
So it can be said now that in 1 minute the distance that Georgina can cover is 1/8 miles. If required it can be converted to decimal value as well.
