Answer:
Total wrapping papers Serena and her grandmother = 51/10
Step-by-step explanation:
Serena's wrapping paper for parents:
- sq meters
Grandmother's wrapping paper:
- sq meters
In order to determine the combined wrapping papers for both Serena and grandmother, all we need is to add both.
i.e.
Total papers = Serena's wrapping paper + Grandmother's wrapping paper
Therefore, total wrapping papers Serena and her grandmother = 51/10
The 3:2 ratio can be calculated by dividing the total by the sum of the factors (3 + 2) i.e. 80/5 = 16
<span>Then multiply the factors by the answer above (i.e. 3 x 16 and 2 x 16) </span>
<span>48:32
