Questions 1 - 10

At a local microchip factory, there are managers for every workers. How many managers are needed for workers?

$20\ \text{managers}$

$21\ \text{managers}$

$19\ \text{managers}$

$18\ \text{managers}$

$16\ \text{managers}$

Explanation

In order to solve this problem, we will create a table of proportions using the following ratio.

$2\ \text{workers}: 5\ \text{managers}$

If we solve for the table, then we can find the number of managers needed for $50\ \text{workers}$ .

Table

The factory will need $20\ \text{managers}$ .

Traffic from the suburbs and farms into a city typically follows an observable pattern. On any given morning there are cars for every trucks. On one particular busy morning there are trucks. How many cars are sitting in traffic?

$21\ \text{cars}$

$22\ \text{cars}$

$24\ \text{cars}$

$28\ \text{cars}$

$29\ \text{cars}$

Explanation

In order to solve this problem we must make a table of ratios. In the question we are given the base ratio:

$7\ \text{cars}:3\ \text{trucks}$

We can use this ratio to make a table.

Cars

According to the table, there are $21\ \text{cars}$ .

At a car production company, manufacturers place tires and transmission on every car in the production line. A manager orders tires, how many transmissions should he order?

$7\ \text{transmissions}$

$9\ \text{transmissions}$

$6\ \text{transmissions}$

$5\ \text{transmissions}$

$9\ \text{transmissions}$

Explanation

In order to solve this problem we must make a table of ratios. In the question we are given the base ratio:

$4\ \text{tires}:1\ \text{transmission}$

We can use this ratio to make a table.

Tires

According to the table, the manager should order $7\ \text{transmissions}$ .

At a car production company, manufacturers place tires and transmission on every car in the production line. A manager orders tires, how many transmissions should he order?

$3\ \text{transmissions}$

$6\ \text{transmissions}$

$7\ \text{transmissions}$

Explanation

In order to solve this problem we must make a table of ratios. In the question we are given the base ratio:

$4\ \text{tires}:1\ \text{transmission}$

We can use this ratio to make a table.

Tires

According to the table, the manager should order $5\ \text{transmissions}$ .

At a local microchip factory, there are managers for every workers. How many managers are needed for workers?

$10\ \text{managers}$

$8\ \text{managers}$

$2\ \text{managers}$

$12\ \text{managers}$

$6\ \text{managers}$

Explanation

In order to solve this problem, we will create a table of proportions using the following ratio.

$2\ \text{workers}: 5\ \text{managers}$

If we solve for the table, then we can find the number of managers needed for $25\ \text{workers}$ .

Table

The factory will need $10\ \text{managers}$ .
