\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?
distributive property for multiplication |
|
commutative property for multiplication |
|
commutative property for division |
|
distributive property for division |
The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
The __________ is the greatest factor that divides two integers.
absolute value |
|
least common multiple |
|
greatest common multiple |
|
greatest common factor |
The greatest common factor (GCF) is the greatest factor that divides two integers.
How many 2 gallon cans worth of fuel would you need to pour into an empty 16 gallon tank to fill it exactly halfway?
| 7 | |
| 6 | |
| 4 | |
| 8 |
To fill a 16 gallon tank exactly halfway you'll need 8 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{8 \text{ gallons}}{2 \text{ gallons}} \) = 4
a(b + c) = ab + ac defines which of the following?

|
distributive property for multiplication |

commutative property for division |
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.
If there were a total of 300 raffle tickets sold and you bought 27 tickets, what's the probability that you'll win the raffle?
| 18% | |
| 10% | |
| 19% | |
| 9% |
You have 27 out of the total of 300 raffle tickets sold so you have a (\( \frac{27}{300} \)) x 100 = \( \frac{27 \times 100}{300} \) = \( \frac{2700}{300} \) = 9% chance to win the raffle.
