Convert all fractions to decimals. Do this by dividing the numerator from the denominator. Ex: numerator/denominator
4/5 = 0.8
6/8 = 0.75
7/12= 0.58
Based on the decimals we converted from fractions. Our answer would be
7/12, 6/8, 4/5
its 100, when it comes to powers you just multiply the number to itself by how many times the power is. 10x10 = 100
C=-2 because you would transfer to the other side making it negative. It can't be a negative so you divide -1 to 2. Making it -2.
