Answer 1

Option B.

B. 5/2 cups of sugar, 19/6 cups of flour

Explanation:

Given that Imogen is baking a cake.

The cake requires two and one-half cups of sugar and three and one-sixth cups of flour.

Sugar required = 2 1/2

To make it improper fraction, we make the integer as a fraction with denominator 2

i.e. 2 1/2 = 2+1/2 =4/2 +1/2

Now we can add these

= 5/2

So 5/2 cups of sugar is required.

Similarly flour required=3 1/6

To make it improper we convert 3 into a fraction with denominator 6.

3=18/6

3 1/6 = 3+1/6 =18/6+1/6 = 19/6

Hence 19/6 cups of flour required.
