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.

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) 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.

19) 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.

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
