100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)
1.) slope=2
2.) slope= -5/4
3.) slope= 7/5
Yes that is true. Each brother can have 25% of the fields. Good luck:)
Is means =
'of' means multiply
percent means parts out of 100 so 48%=48/100=4.8/10=0.48/1=0.48
so it is
336=0.48 times something
divide both sides by 0.48
700=something
the numbe ris 700
There are 14 boys, therefore 16 girls.
