The first four are the correct ones
Say for example, you have the improper fraction 18/7
The first step is to find out how many times 7 fits into 18
This looks like flipping the fraction, 7/18 = 2 whole times with 4 parts left over
The 4 left over gets put in front of the original number (7) to give 2 4/7
To check if you have done it correctly, multiply the whole number (2) by the denominator ( 7 ) and then add the numerator.
2 x 7 = 14 + 4 = 18
Hope this helps
A cube has 6 faces. The surface area of a cube is 6 times the area of one face.
SA = 6s^2
SA = 6 * 6cm^2
SA = 6 * 36cm^2
SA = 216cm^2
12= -12
-1/2= 1/2
.25 =-.25
-27=27
0=0
