  1. first of our master hosting this week is alright.
  2. She out of first of all simplify ratio.
  3. Let's start with the basics.
  4. So, first of all, what is racial?
  5. Well, it's the really the comparing of two different amounts
  6. used to make something.
  7. Let's have a look here.
  8. So which are five ratios in that sequence there?
  9. That's right.
  10. It's the ones that are written with a cone on
  11. divide in the month.
  12. This is nothing to do with the cardinals that we
  13. use electricity, so don't get confused.
  14. Now what we simplify ratios we use.
  15. A very familiar golden rule is the golden rule that
  16. we use quite commonly fractions as well.
  17. In fact, it's so common to us that attend to
  18. only ever write very first word.
  19. Whatever you do toe.
  20. One thing you do to another, as I regularly see
  21. regularly say Masses about Fallon.
  22. Sir, Let's have a look here at my imaginary fruit
  23. salad. So in my salad for every 12 apples that
  24. I use, I use full bananas.
  25. And of course, when I do this, I use 16
  26. fruit in total.
  27. Now, if I was going to simplify this all I'm
  28. saying to myself What number can I divide most of
  29. this by?
  30. So when I look at 12 and I look up
  31. four, I think, What's their common factor?
  32. What number goes into both of them?
  33. And, of course, it's full 12 divided by four is
  34. 34 Divided by four is one on that we tend
  35. to find in class.
  36. It's helpful to write news in our arrows because it
  37. helps us to single with you could also raise show
  38. with more than one number in it.
  39. So in this case, we've got to.
  40. This time I've got a family group.
  41. So I got for every 20 adults.
  42. They might be six boys, and that might be eight
  43. girls, which leaves a family group of 34.
  44. I'll go to simplify this.
  45. I've got to find a number that is a common
  46. factor to 26 8 Another number.
  47. What number goes in tow All of those numbers.
  48. I could look at six, but six doesn't go into
  49. eight or 20.
  50. I could look at three three doesn't go into 8
  51. 20 Although it goes into six.
  52. The only number I can think of that going to
  53. do all of them is to.
  54. So I've divided all of them by two.
  55. And that is me.
  56. Simplifying my race is a simple is that using that
  57. method Whatever you do to one you do to the
  58. other, remember to draw your arrows, Tashi.
  59. The first sheet here and then we've got a second
  60. sheet. In addition, you'll find that authorship might be easier
  61. than the second least the hope.
  62. Enjoy this.
  63. This should be a straightforward reminder as ratios for some
  64. of you.
  65. And because of that, I am to post another ratio
  66. task as well.
  67. Enjoy. And I look for to see your work.
