Another way to work out the last question. 10% of 620 = 62 (divide by 10) 1% of 620 = 6.2 (divide by 100 or move decimal one place to the left) 6.2+6.2=12.4 (2%) 0.5 % of 6.2 = 3.1 (divide by 2) 62 (10%) + 12.4 (2%) + 3.1 (0.5%) = 77.50 (12.5%) 620 -77.50 = 542.50
The ratio is 2:2:1. (S,m,l) we take the amount of 50 and divide by 5 (2+2+1) this gives us 10, to find out how many Small we then multiply by 2 (the first 2 in the ratio 2:2:1) which gives us 20 ☺️ I hope that helps
@@mrmaths98 Sure does thank you. I was in a good place before with your and another's videos. Was due to sit exam then I got bloody covid for the first time and because of dyscalculia maybe I basically forgot it all. Test next Monday, I'll let you know
Thanks for taking us through the exam, I’m working on this with some students and this will come in handy. I would have taken a different approach on 2 of these questions myself (I hope you don’t mind me saying!) Q6 I would have worked out the area of the big rectangle (6m x 7.5m) and then take away the area of the triangle (2m x 4.5m / 2). Not much different to your method to be fair but has less steps. Q7 I like your method but I think it would be too complicated for some students. I would just keep it simple and divide £620 by 100 and then multiply by 12.5 which gives £77.50 and then take that off the £620 for £542.50. Enjoyed the video though I’ll be watching more of these with my students and talking through different ways of thinking. Thanks!
The government really got me stressing over the fraction of custard creams. THAT I DONT EVEN GET TO EAT. they really got me learning about nothing. Edit: Oh nvm Fractions are quite easy. Hehe 😭 I freaked out a little sorry.

10% of 620 = 62 (divide by 10)
1% of 620 = 6.2 (divide by 100 or move decimal one place to the left)
6.2+6.2=12.4 (2%)
0.5 % of 6.2 = 3.1 (divide by 2)
62 (10%) + 12.4 (2%) + 3.1 (0.5%) = 77.50 (12.5%)
620 -77.50 = 542.50
These videos are super helpful, Thank you so much
Thank you. i really like the way you explain.
Thanks you u are the best
thank you
I watch this everyday
14:30
the 20/100 simplified is 1/5
Question 5 12.25, you say "2 x 10 = 20", I have no idea where either of those numbers came from.
The ratio is 2:2:1. (S,m,l) we take the amount of 50 and divide by 5 (2+2+1) this gives us 10, to find out how many Small we then multiply by 2 (the first 2 in the ratio 2:2:1) which gives us 20 ☺️ I hope that helps

Couldnt for Q7 you have just found 12.5% by dividing, its a lot quicker, you can find 0.5% by dividing by 200

Thank you for the support and suggestions ☺️
Wait how did you get the 10? For question 5
Same here what he has done to the ratio. 2+2+1=5 ??
how did you get the 0.875
Which question are you referring too? can you put a time stamp in your reply so I can help you further 🙂
Very complicated solution😄 y not simply multiply 620 x .125=77.50
620-77.50=542.50

Was question 4 not 17 over 60?
I don’t understand how you get 0.875
Which question would that be my friend, if you give me a time stamp I can explain 🙂
I didn't either, but 0.125 is substrates from 1 so the remainder is 0.875
So 1 - 0.125 is 0.875 as a decimal. Hope this helped you
Subtracted *
Question 7 is confusing me a bit
Yes i see what you mean.. he said 2x5 when it should be 2x7..
Q5 completely don’t understand
I admit it does look a bit messy and I apologise for it, What part are you having trouble with? Maybe I can help 😊
