1

What is \( \frac{1}{5} \) x \( \frac{2}{8} \)?

72% Answer Correctly
\(\frac{1}{20}\)
\(\frac{1}{4}\)
\(\frac{1}{9}\)
\(\frac{1}{21}\)

Solution

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{1}{5} \) x \( \frac{2}{8} \) = \( \frac{1 x 2}{5 x 8} \) = \( \frac{2}{40} \) = \(\frac{1}{20}\)


2

What is \( 2 \)\( \sqrt{12} \) + \( 6 \)\( \sqrt{3} \)

35% Answer Correctly
12\( \sqrt{12} \)
8\( \sqrt{12} \)
8\( \sqrt{4} \)
10\( \sqrt{3} \)

Solution

To add these radicals together their radicands must be the same:

2\( \sqrt{12} \) + 6\( \sqrt{3} \)
2\( \sqrt{4 \times 3} \) + 6\( \sqrt{3} \)
2\( \sqrt{2^2 \times 3} \) + 6\( \sqrt{3} \)
(2)(2)\( \sqrt{3} \) + 6\( \sqrt{3} \)
4\( \sqrt{3} \) + 6\( \sqrt{3} \)

Now that the radicands are identical, you can add them together:

4\( \sqrt{3} \) + 6\( \sqrt{3} \)
(4 + 6)\( \sqrt{3} \)
10\( \sqrt{3} \)


3

4

A machine in a factory has an error rate of 7 parts per 100. The machine normally runs 24 hours a day and produces 10 parts per hour. Yesterday the machine was shut down for 2 hours for maintenance.

How many error-free parts did the machine produce yesterday?

49% Answer Correctly
97.9
147.2
204.6
144

Solution

The hourly error rate for this machine is the error rate in parts per 100 multiplied by the number of parts produced per hour:

\( \frac{7}{100} \) x 10 = \( \frac{7 \times 10}{100} \) = \( \frac{70}{100} \) = 0.7 errors per hour

So, in an average hour, the machine will produce 10 - 0.7 = 9.3 error free parts.

The machine ran for 24 - 2 = 22 hours yesterday so you would expect that 22 x 9.3 = 204.6 error free parts were produced yesterday.


5

a(b + c) = ab + ac defines which of the following?

74% Answer Correctly

commutative property for multiplication

distributive property for division

commutative property for division

distributive property for multiplication


Solution

The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
