What is a numerical expression?

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Consider the numbers be: x and y

Given that sum of two decimal numbers is 3.9. Their difference is 0.9 and their product is 3.6

Then the system of equation;

x+y=3.9

x-y=0.9

Adding both the equation we get;

2x = 4.8

x = 2.4

Now for the value of y.

2.4+y=3.9

y=3.9 - 2.4

y = 1.5

Therefore, the two numbers are 2.4 and 1.5 respectively.

1 is the tenths place.
2 is the hundredths place.
3 is the thousandths place.

And so on.

So... unfortunately, you cannot write 0.02 in tenths.

First you see how many zeroes there are. 2 right, now, which number has two zeroes? 100 has 2 zeroes so that definitely fits. So, you put 2 as the numerator and 100 as the denominator and that is how you convert it.

Think of a pizza. If there are 5 slices and you have all 5 of them, then you have the whole pizza.

Now, instead of the pizza having 5 slices, it now has 10. Since the pizza is still the same size, the pieces are going to smaller. If you have 9 slices out of the 10, you won't have the whole pizza.

This is why 5/5 is greater than 9/10.
