Question

Trying to find a new way to explain rational numbers - changing fractions to decimals (and vice versa) and graphing them on a number line

Answer 1

changing fractions to decimal = divide the numerator by the denominator

changing decimals to fraction= transform decimal number to whole number by moving the decimal point, then divide the transformed whole number by the power of 10 equivalent to how many times you moved the decimal point,
example: .33
(1) move the decimal point to transform into whole nuber
33
(2) divide by equivalent power of 10
33/100
(3) simplify

Answer 2

Okay - I understand that part

Answer 3

I think what's confusing me about this lesson is that the book tells me to graph the fractions on a number line to determine which one is bigger, but they aren't like fractions: for example ...

Answer 4

The book shows a number line where they've graphed 2/3 and 7/10 to determine which one is bigger. Wouldn't it be easier to just change them into like denominators first?

Answer 5

2/3 means = get 2 to 3. .

for example in the number line the point is 2 of 3
