Respuesta :

Auspicious

Answer:


Step-by-step explanation:

1. Sugar : Pecans

           1 : 4

2. 120 : 800

    15 : 100

    3 : 20

3. 1 : 4

1 + 4 = 5 (if you add both sides of the ratio, also, if you multiply/divide on each side of the ratio by the same, it works)

20, total number of hours, / 5 = 4

multiply by 4 on both sides

4 : 16

sarah spent 4 hours on the project
