2/10 in simplest form:
First, we can start out by finding the greatest common factor (GCF) of the numerator (2) and the denominator (10). This should always be done when simplifying a fraction the quickest way. Let's list out the factors of each number and find the common ones.
Factors of 2: 1, 2
Factors of 10: 1, 2, 5, 10
The GCF is 2, considering that 1 and 2 are the common factors, but 2 is the greatest.
Second, our last step is to divide
our numerator and denominator by the GCF (2) to find out our simplified fraction.

Answer in decimal form:
4 * 1,000,000,000 = 4,000,000,000
5 * 1,000,000 = 5,000,000
9 * 10,000 = 90,000
8 * 100 = 800
7 * 1 = 7
put it all together
4,005,090,807

Answer:
180
Mathematically, 10 times less than 20 would be: Take 20, subtract (10 x 20). Answer: -180.
Ratio= 2:3 add them together= 5. 20 divided by 5= 4.
4x2=8
3x4=12
