1/5 of 20 is $4. So, 20-4=$16 remaining.
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining.
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07
Answer: Ken has $6.07 left after all his purchases.
There are 3 different possibilities for cones and 5 flavors of yoghurt.
You would do 3*5 to calculate the sample space, which is 15.
It should be A 6,1 because 6 is the x-axis and 1 is the y-axis
25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81
Looking at the question we can see that it says:

We should know what these symbols mean:
stands for something less than the other, for example:
We can say that 2 is less than 5 so in a symbolic form it can be written as,
Similarly,
stands for something greater than the other, for example:
We can say that 7 is greater than 5, in a symbolic form it can be written as,

So here,
means that, 42153 is greater than 35214.
