7) 1/2, 5/10 = 1/2 because 10÷2=5 and 2÷1=2
8) 1/3, 4/12 = 1/3 because 12÷3=3 and 3÷1=3
9) 1/4, 2/8 = 1/4 because 8÷2=4 and 4÷1=4
10) Simplest Form, 100÷3 still equals 3/100
11) 7/10, 70/100 = 7/10 because the zeros cancel out.
12) Simplest Form, it cannot reduce any further
13) 1/6, because 12/12 (or 1) - 10/12 = 2/12 (or 1/6)
14) 3/4, 8-2=6 meaning that 6 out of 8 kittens are not white, 6/8 = 3/4
15) Simplest form, meaning they can be reduced no further
16) Greatest common factor, this means that there is a number between the numerator and the denominator that they can be reduced by
17) C, because 12/3 = 4
