5. What is the decimal representation of 1/4?

0.1.

0.01.

0.25.

0.5

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.

9. What is −7m(−4)m3?

To solve −7 × (−4) × 3, start by multiplying the first two numbers:

−7 × (−4) = 28, because the product of two negative numbers is positive.

Then multiply the result by 3:

28 × 3 = 84.

This order of operations follows standard multiplication rules: proceed left to right. The presence of parentheses reinforces which numbers to multiply first but does not change the order here. Thus, the final answer is 84, and it's mathematically correct.

10. What is the value of 2(4 + n) - 5 when n = 0?

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.

16. 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."

The statement says "the quotient of a number t and 7," which means t divided by 7. In math, division is shown using the slash symbol /, so that becomes t / 7. Then it says "plus 2," so we add 2 to the expression, making it t / 7 + 2. Finally, "is -4" means the expression equals -4. So the full mathematical sentence becomes t / 7 + 2 = -4, and this correctly matches the original statement.

18. Determine the result of the expression: What is ∣−10−(∣4∣+1)∣?

-15

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.

19. How can 0.55555... be represented as a fraction?

5/9

5/10

1/2

1/3

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.

20. Which is greater?: -3/7 or -0.375

-3/7 < -0.375

-3/7 > -0.375

-3/7 = -0.375

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 −3/7
