That video taught me more than the highschool in wich I had to study 4 hours of maths every week for four years.

[Imahijabi]

Thanks for the help! Do you know if these types of questions will be on a calculator or non calculator test bc I have both of these tests and I dunno which test this topic will be on

[kshitijkanukolanu]

Beautifully put together. This helped me cover the concepts which I had missed in class.

[nethra]

thank you so much!!! going to really help me on my test!

[humaymahyaser]

if u dont mind when would u mutliply or divide best buy or it doesnt matter which one just as long you find the same factor if your multipling

[hajrahawais]

do you have to do it that way because i worked it out by multiplying the litres by 2 and the prices by 2 and found out which price was better

[Motupaltubajrangi]

tysm you are very helpful I am revising for my end of yr 9 exam is there anything u posted that could help a lot with it?

[tonycgames]

this was very helpful for my maths revision thanks i did well thanks to you

[DoughBear]

If i get the same price a bottle for two different quantities. Which one would br the correct answer for a test?

[Golgothaable]

Would this be a calculator question? Otherwise one would have to do long division. Can you do a video on long division and multiplication please?

[MutePenguin]

Is this for a Calculator or non calculator paper?

[jaimecartledge]

so underated, better than my math teacher

[Golgothaable]

Third method is to convert the litres to ml so as to get 1.2 litres the difference is then 0.015 per ml compared to 0.016 per ml and 0.015 x 120ml = £1.80.
