4 times 1 = 4 so the top one would be 4/12, but i can't help with the rest because i don't understand what they are asking for
x+y=17000 (x.7+y.15)/100=2000 (7x+7y)+8y=200000. 8y=200000-17000.7 y=61.5.5.5 17000-y=9375=x x=9375
12598 rounded to the nearest thousands is 1260
Number 2 is 1.00 and Number 3 is 1.50
Area of a triangle: (b*h) /2
So :
(14,5 * 10.5) /2
=152,25 /2
= 76.125
