Math Questions

Here are the three math questions we had to do.



The first one is  3/4 x 1/3.

So to get the answer you just have to multiply the numerators, and the denominators. So 3x1=3. And 4x3=12. So the answer is 3/12. What is 3/4 of 1/5

So the picture for this question looks like this.


So you see how you colour in 3/4, and then only take 1/3 of the 3/4; and that equals 3/12
What is 2/5 shared with 2/3



Okay so the next question is 2/5 / 2/3
So to get the answer to this question, you have to get a reciprocal.

So the answer to this question is 3/5

So now to get the picture it



Sorry if you can't see it a bit.......
 

So now for the final question. 5/6 / 1/3

So the reciprocal for this question is 3/1. So 5x3 and 6x1 = 15/6= 2 and 1/2.
How many groups of 1/3 are in 5/6 
 
 
So that's the picture.
