I am learning to write a number problem using fractions.
I got the problem 1/4 of 860.
In swimming lessons there are 860 people. The manager wants to split them up in four groups how many people are in each group?
How I got the answer.
There were two ways:
1. I divided it by 4.
2. I halved 860 and that equalled 430 then I halved 430 and it equalled 215.
So 1/4 of 860 is 215.
How I checked it was correct?
I multiplied 2x215 but I also multiplied 430x2 which gave me the answer 860.
