Urgent - how to do this simple maths question (%)

[meandmycrew]

I thought you'd find 1% and then times that by 7 to find your 7%.

Once you found your 7%, add it to the £14.50.

BUT, I can't find 1% of £14.50... it's 0.145p

10% of £14.50 is £1.45 but that's no good either as I can't half it for 5% as the question wants 7%!

Thanks so much

Divide by 100 and multiple by 107

£15.515, or £15.52 pence?

So, If 10% of £14.50 is £1.45, then to find 1% you need to move the decimal place one point ie 14.5p.

hth

How is £15.151 the same as £15.52?

Multiply by 1.07

X 1.07 if you can use a calculator

But your 1% method is right. Are you thrown off because you have a fraction of a pence answer?

1450x1.07 to give you answer in pence

BUT, I can't find 1% of £14.50... it's 0.145p

You have found 1%, now multiply by 7 and add it on as you planned. Your method is fine. Your answer isn't a whole number of pence so round it up to the nearest pence.

It's rounded to the nearest whole penny

Yes, I would've just found the 1% and times it by 7... but it doesn't work because you can't have half a pence for example

£15.515 rounded up is £15.52

Thanks so much!

It doesn't say to round it which is why I was confused

14.50x1.07

Maths is honestly not my forte so hopefully someone brighter than me comes along but I would say you are correct. You would just round up surely.

So 0.145 x 7 = 1.015 so £1.02

£14.50 + £1.02 = £15.52 on the door price

You've got a typo. It's not £15.151, it's £15.515.

£15.515 rounds up to £15.52

7% of £14.50 is £1.015

£14.50 + £1.015 is £15.515

Round up to £15.52

Just to prove my previous comment... i started typing that when you had no replies 🤣

1% is 14.5p. (The 0.145 figure is correct, but it's 0.145 pounds, not pence.) So
7 x 14.5 is £1.015 (so I'm guessing you round up?)
So the new price is £15.52, I think!

Everyone is right -- just going to point out though that 1% of £14.50 is 14.5p, not 0.145p, in case that was holding you up.

I'm rubbish at maths. There will be more elegant, quick ways to do it but I'd do it this way.

1% of £1 is 1p, so 1% of £10 must be 10p and 1% of £4.50 must be 4.5p so
1% pf £14.50 must be 14.5p. Multiply that by 7 to get 7%. Again, I break it down into 7 x 10p is 70p; 7 x 4p is 28p and 7 x .5p is 3.5, added together that's £1.015. Add that to £14.50 = £15.51,5p so £15.52p.

No idea if this is right.

Ooo thank you! Got if completely once I realised I could round up

Does anyone know how to do this? I am thrown off because with ratio, I thought you'd just as 2:3 together, which is 5

So for example 640g divided by 5 is 128g. 128g x 5 is 640g

880g divided by 5 is 176g. 176g x 5 is 880g

So why does he need more? Do I just take 640g away from 880g, which is 240g?

keep it simple, multiply by 1.07

Thank you everyone! I was really stuck

I am trying to get a maths qualification before I am unleashed into a uni as you can tell, I am no maths whizz and I probably wouldn't get Year 5 maths classes

2nd q answer is 80g

640/2 - 320
then x 3 =960

960 - 880 = 80g

Divide the butter by 2 to find 1 part of the ratio is 320g

Flour is 3 parts of the ratio so multiply 320g by 3 to get 960g

So for 640g of butter he would need 960g of flour....you can work out how much more he would need to buy!
