If 3/2 divided by 1/4 =n , then n is between
kari74 [83]
OK, this written in numbers is

\frac{3/2}{1/4} =n

But, fractions can not divide.  So we need to multiply one by the reciprocal of the other.  The reciprocal of a fraction is itself flipped upside down.  For example, the reciprocal of 1/2 would be 2/1.  

So, we will multiply 3/2 by 4/1.  We know how to do this, it is simply 3/2*4=12/2=6.

So, the answer is n = 6.  That would be answer c, because 6 is between 5 and 7.

The length of a rectangle is 5 in longer than its width. if the perimeter of the rectangle is 34 in , find its area.
shtirl [24]
Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5 
width(w)= w

1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in

l= w+5
l= 6+5
l=11 in


A= lw= (11)(6)= 66in²

Answer:
Area of rectangle is 66 in².
