15% of 280?
I was able to do this once, but I've forgotten how. Can someone explain it to me again? I'm only in 7th grade, so please don't bully me.

How do I do this task (analytic geometry)?
I don't understand how to go about this. For an equilateral triangle, you calculate the dot product, but what do you do for an equilateral triangle? How do you do this with the area?
10% are (stash a zero) 28, 5% half thereof, i.e. 14
then 15% is 28+14 = 42
Yes, 42 is the answer to the QUESTION!
42, however, you can easily answer everywhere and probably moderators wouldn’t even delete it. You probably get the star automatically.
10% of 280 = 28
5% is thus 14
And how much are 15% of 280 now?
100 % = 280
1 % = 2.8
15 % = 2.8 × 15
Thank you
15% =3/20
280/20=14
14*3=120
280*15%=42
Or the same other way:
How much is 1% of 280? Right, 2.80
Now 15 x 2.80. There’s 42 again.
Divided by 100 times 15. Jeez, 7th grade.
Where are you going? 13 years!
