Watch: Roaring ratios
Football coaches and commentators use all sorts of maths to calculate how well their team is performing - including ratios.
Find out how much you know about ratios in this short video presented by Gary Lineker from âMatch of the Dayâ and Ben Shires from C±«Óătv âKickaboutâ.
You'll need a pen or a pencil and some paper to note down your answers. There's a 30 second timer so you'll need to stay on your toes!
Gary Lineker: Football is full of numbers. 11 against 11, 4-4-2, goal tallies, so, next time you watch a football match, look out for the hidden maths.
Let's go over now to the Kickabout Studio to see what today's Maths Of The Day topic is.
Ben Shires: Thanks, Gary!
Today's Maths Of The Day topic isâŠRoaring Ratios!
A ratio tells you how much of one thing there is compared to another.
There are 27,000 people in the crowd for a match between Leicester City and Stoke City.
24,000 are roaring for Stoke and 3,000 are roaring for Leicester. So that means there are 8 Stoke fans for every single Leicester fan.
That gives a ratio of 8:1.
Back to you in the studio, Gary.
Gary Lineker: Thanks, Ben.
So, let's try a few more ratios.
Question 1 - For every 3 minutes Manchester City attacks, they spend 2 minutes defending, so their attacking-to-defending ratio is 3:2.
If City play this way for 20 minutes, how long do they spend attacking?
In 5 minutes, City spends 3 minutes attacking and 2 minutes defending.
20 minutes is 4 times as long, so they spend 4 x 3 minutes attacking, which makes 12 minutes.
Question 2 - If City played the same way for 45 minutes, how long would they spend defending?
They will still spend 3 minutes out of every 5 minutes attacking and 2 minutes defending.
45 minutes is 9 times as long so they spend 9 x 2 minutes defending which makes 18 minutes.
That's all from me for now. Keep practising and you'll soon be 100% successful.
