B)To get the answer to this Question -
All you have to do is multiply the first number (4) by the numerator (1) but the demoniator always stays the same so you would get the answer (4/2) then you have to simplify if possible (1 2/2).
C)To Answer this question -All you have to do is use a picture (or number line) to determine the answer. Using a picture all you have to do is make a square. The number of squares going down is the same number as the single number (2) and the squares going across is the same number as the first denominator (4). Then shade in the the number of the single number (2) and use a different colour to shade in the number of the numerator (1) over the already shaded part to get your answer (1/8)
D) To answer this question -
All you have to do is shade in the number of squares that match the single number, 5, then use a different colour to re-shade the number that is the numerator, 1. Then you would get 1/15 as your answer.
