Answer:
3. 82.5 miles
4. 12 sausages or 2 sausages (read below)
Step-by-step explanation:
To find 3, we know that there is a ratio of 2 inches of clay to 3 miles of the actual river, or 2:3
Knowing this, we need to divide 55 by 2 in order to find how many pairs of 2 there are in total.
Once we do this, we get 27.5 Even though this is not an even or whole number, we can still apply the ratio by multiplying this by 3.
27.5*3 is 82.5, which when applying the units, we see that Herbert's 55 inch model represents a 82.5 miles long Guadalupe River.
To find 4, we take the given ratio of 5 pepperoni, 3 sausage, and 6 mushrooms, or 5:3:6
Assuming that "4-part mushrooms" means 4 respective ratios of mushrooms, we can see that there would be 24 mushrooms in total. This is quite simple to continue from, and we just need to multiply 3 sausages by 4 to get twelve sausages total in their respective ratio.
If "4-part mushrooms" means only 4 mushrooms however, this is entirely different and we must use the ratio to help us differently. Seeing that there is a ratio of 3:6 for sausages and mushrooms, this simplifies to 1:2 or 1/2.
This means that if there are 4 mushrooms, there will be two sausages.
