mixed number
I'll help with #1

Convert 6.35 to a mixed number.

A mixed number is a number in the form of a whole number and a fraction such as 1 3/4 which can also be written as 1.75.

To convert 6.35 we need to convert 0.35 to a fraction. .35 is the same as 35/100, now we need to simplify 35/100 to its simplist form. It is easy to see that 35 is divisible by 5 (7x5=35) and 100 is also divisible by 5 (20x5=100).

so we can convert 35/100 to 7/20 and our solution is now:

6 7/20, a mixed number.

Lets express them as fraction.
I will use first number as example.

As you can see 6.35 is consisted of number 6 and 0.35 (6.35 = 6+0.35).
6 is a 6, and 0.35 is 35/100.
So 6.35 expressed as factor is $\displaystyle 6\frac{35}{100}$.
35/100 equals to 7/20 (after dividing up and down number with 5).
So $\displaystyle 6.35=6\frac{7}{20}$.

Other numbers are also done similar.
So we have:
2. $\displaystyle 0.85=\frac{85}{100}=\frac{17}{20}$.
3. $\displaystyle 0.48=\frac{48}{100}=\frac{12}{25}$.
4. $\displaystyle 5.125=5\frac{125}{1000}=5\frac{1}{8}$.
5. $\displaystyle 0.0625=\frac{625}{10000}=\frac{1}{16}$.
6. $\displaystyle 1.225=1\frac{225}{1000}=1\frac{9}{40}$.
