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 is…Roaring 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.
