Grade 6th on Khan Academy: By the 6th grade, you’re becoming a sophisticated mathemagician. You’ll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.)

  1. This explanation is very weak imo. Ratio is a multiplicative comparison between quantities. It says how many times greater is one thing than another or what fractional part is one thing of another. For example ratio of 12 to 4 is 3. 12 is 3 times larger than 4. (“3 times” is the ratio). Ratio of 4 to 12 is 1/3, because 4 is the third part of 12. Thats why to find a ratio we have to divide.
     Ratio can be also understood as a composed unit (for example 4$ per one orange, 8$ per 2 oranges etc).

  2. i had to watch this for school and it dragged on so i just speed it up as fast as possible so i could finish early and play games lol

  3. Easier way of explaining what ratios it’s what the total of the apples are then to the oranges in a form of a fraction or decimal

  4. Useful, still. The apples to oranges 6 to 9 is a little on the nose there.

    This did help with helping my little brother. Thanks guys.
