This problem is proportional! for every 1 second 12.5 jellybeans are made!
Perimeter of square : p = 4a.....
p = 4(x + 2)
p = 4x + 8
perimeter of rectangle : p = 2(L + W)
p = 2(3x + 2 + x - 1)
p = 2(4x + 1)
p = 8x + 2
so if the perimeters are te same, lets set them equal to each other and solve for x
4x + 8 = 8x + 2
8 - 2 = 8x - 4x
6 = 4x
6/4 = x
1.5 = x
the square : p = 4x + 8.....p = 4(1.5) + 8.....p = 14 meters
the rectangle : p = 8x + 2....p = 8(1.5) + 2.....p = 14 meters
so she bought 14 meters of fencing <==
36/4 = 9 per hat
56/7 = 8 per hat
no, they are not equivalent
Two <em>possible answers</em> are:
5/16 and 3/8.
Explanation:
To create a fraction equivalent to a given fraction, you multiply the numerator and denominator by the same number. This means for 5/8, we could have:
5/8; (5*2)/(8*2)=10/16; (5*3)/(8*3)=15/24; etc.
For 1/2, we could have:
1/2; (1*2)/(2*2)=2/4; (1*3)/(2*3)=3/6; etc.
