We have a ratio of candies in a bowl.
00:04
So we have a bowl of candies, some are green, some are red, and some are blue.
00:11
The ratio here is 4 to 3 to 9.
00:16
And we know that if we add up the red and the green, we have 196.
00:24
How many blue ones are there? so there are some different ways you can go about this, different ways of manipulating these numbers.
00:31
One way is to group these together and now say, okay, we've got this and this, and together they make up seven.
00:41
So the ratio of red plus green to blue is seven to nine.
00:48
So the fastest way would be to do this, take 196 and then multiply it by nine over seven.
00:58
So you would say, okay, 196, make some space.
01:07
This is the ratio.
01:08
You want to know what goes here.
01:11
If there's 196 of these, how many of these are there? and for that, you would calculate 196 over 7 and then multiply it by 9.
01:23
Because you would have this middle one where you have 196 over 7 to be question mark over 9...
