Answer 1

Answer: area=(1/2)bh
b=legnth of base
h=legnth of height

we are given
b=3 and 1/4
area=12 and 2/5

covert everybody to improper fraction

b=3 and 1/4=3+1/4=12/4+1/4=13/4
area=12 and 2/5=12+2/5=60/5+2/5=62/5

area=(1/2)bh
62/5=(1/2)(13/4)h
62/5=(13/8)h
times 8/13 both sides (13/8 times 8/13=104/104=1)
496/65=h

What is greater 1\3 or 30%?

Answers

To compare we can tranfrom 30% info fraction
30%= $(30)/(100)= (3)/(10) = (3*3)/(10*3) = (9)/(30)$
$(1)/(3)= (1*10)/(3*10)= (10)/(30)$
Now we can compare
$(9)/(10)< (10)/(30)$
So 1/3 is greater than 30%./

1/3 is greater because 1/3 equals 33.3333333333 and 30% is 30%. So therefore 1/3 is greater than 30%.
