What is the decimal representation of 1/4?
-
0.1.
-
0.01.
-
0.25.
-
0.5
Correct Answer
A. 0.25.Explanation
A fraction can be converted into a decimal by dividing the numerator by the denominator. In this case, divide 1 (the numerator) by 4 (the denominator): 1 ÷ 4 = 0.25. This means that 1/4 is equal to 0.25 as a decimal. Decimals represent parts of a whole, and 0.25 corresponds to one-quarter of 1. This value is often used in daily measurements, such as money or weights, making it an important concept in arithmetic. Thus, the decimal representation of 1/4 is accurately written as 0.25.Rate this question:

-
3
Correct Answer
A. 3Explanation
To evaluate the expression 2(4 + n) - 5 when n = 0, we substitute 0 for 'n'. This simplifies the expression to 2(4 + 0) - 5. Following the order of operations, we evaluate the parentheses first, resulting in 2(4) - 5. Next, we perform the multiplication, giving us 8 - 5. Finally, we subtract to get the answer, 3.Rate this question:

What is the mathematical expression for the statement: The quotient of a number t and 7, plus 2, is -4?
-
7/t - 2 = -4.
-
T/7 = 2 + (-4).
-
T/7 + 2 = -4.
-
Both "a" and "b."
Correct Answer
A. T/7 + 2 = -4.Explanation
To translate the given statement "The quotient of a number t and 7, plus 2, is -4," we need to find the correct algebraic expression that matches this description.
The statement can be broken down as follows:
"The quotient of a number 𝑡t and 7" means t/7
"plus 2" means we add 2 to the quotient.
"is -4" means the expression equals -4.
Putting it all together, we get:
t/7+2=-4Rate this question:

-
15
-
-15
-
7
-
5
Correct Answer
A. 15Explanation
To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS) and remember that the vertical bars represent absolute value, which is the distance of a number from zero, regardless of sign.
Innermost absolute value: ∣4∣ = 4
Parentheses: 4 + 1 = 5
Subtraction: -10 - 5 = -15
Outermost absolute value: ∣-15∣ = 15
Therefore, the result of the expression is 15.

How can 0.55555... be represented as a fraction?
-
5/9
-
5/10
-
1/2
-
1/3
Correct Answer
A. 5/9Explanation
To express the repeating decimal 0.55555... as a fraction and simplify it, we can set up the following equation:
x = 0.55555...
Now, we'll subtract this repeating decimal from 10x, which should eliminate the repeating part:
10x - x = 5.55555... - 0.55555...
9x = 5
Now, divide both sides by 9 to solve for x:
x = 5/9
So, the repeating decimal 0.55555... is equal to the fraction 5/9.Rate this question:

Which is greater?: -3/7 or -0.375
-
-3/7 < -0.375
-
-3/7 > -0.375
-
-3/7 = -0.375
Correct Answer
A. -3/7 < -0.375Explanation
To determine which is greater, −3/7 or -0.375 we need to compare the two values. We can convert -3/7 to a decimal for an easier comparison.
Convert -3/7 to a decimal
-3/7 ≈ 0.4286
Compare the two decimals:
−0.4286 (approximate value of −3/7)
−0.375
Since −0.4286 is less than −0.375, −0.375 is greater.
Therefore, −0.375 is greater than −3/7Rate this question:
