Pre-Algebra 20 - Converting Repeating Decimal Numbers to Fractions

Decimal numbers with an infinitely repeating sequence of digits after the decimal point can be converted into fractions. This chapter explains why.

Because of my cancer, I had to miss a few days of school, and this really helped me with my grades.

The amount of times youtube has taught me something better than school ever did is frightening. But this is an amazing lesson, super useful especially when my calculator refuses to turn crap into fractions.

Mechanical Engineering Major here (university student).
Found this video quite helpful. I never actually learned this is any of my elementery to highschool classes, and I usually just used a calculator to convert the number into a fraction. Being able to do this (first on paper and now in my head) saves a couple of seconds while writing out solutions on homework and on exams for, say, my Fluid Mechanics class. So thank you!!!
(Extremely useful when I need to maintain a certain level of precision which is lost on rounding but which also costs a tiny bit of time to regenerate in my calculator from previous steps. it's not much but, when using pipeflow equations for example, it stacks up quickly)

If anyone is stuck on WHY and HOW we got 9. Here is HOW;[10x - x = 10x - 1x= 9x] the missing piece is the #1 no body stated it, everyone here is only paying attention to the fact the it just 9 without actually explaining how we got to 9. Here the WHY remember [x is the same as 1x] #1 is the multiplicative identity in multiplication.
