sveticcg [70]

Answer:

$2\frac{38}{125}\ teaspoons$

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

so

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

$\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons$

Simplify

$\frac{288}{125}\ teaspoons$

Convert to mixed number

$\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons$

If you scale down the ratio on the left, what will you get for the unknown quantity on the right? 434 miles14 gallons = ?2 gallo

jarptica [38.1K]

Answer:

option (A) 62 miles

Step-by-step explanation:

Data provided in the question:

Ratio on the left = 434 miles : 14 gallons

ratio on the right = ?? : 2 gallons

Now,

The ratio on the both sides are equal

let the unknown value in the ratio be 'x'

Now, the ratio a : b can also be represented as $\frac{a}{b}$

therefore,

434 miles : 14 gallons = x : 2 gallons

or

⇒ $\frac{\textup{434 miles}}{\textup{14 gallons}}$ = $\frac{\textup{x}}{\textup{2}}$

or

⇒ x = $\frac{\textup{434 miles}}{\textup{14 gallons}}\times2 gallons}$

or

⇒ x = 62 miles

Hence,

the correct answer is option (A) 62 miles
