Estimation Math Practice Problems & Exercises Online

To solve this problem, we'll follow these steps:

• Step 1: Convert the fraction $\frac{80}{11}$ into a decimal number.
• Step 2: Multiply the resulting decimal by 100 to find the percentage.
• Step 3: Identify the correct choice from the provided options.

Now, let's work through each step:
Step 1: Divide $80$ by $11$. The result is approximately $7.27$, as $11$ goes into $80$ 7 times with a remainder.
Step 2: Multiply $7.27$ by $100$ to convert it to a percentage: $7.27 \times 100 = 727\%$. However, since the question asks for an approximation, use rounding to the nearest hundred percent: approximately $800\%$.
Step 3: Among the choices provided, the closest approximate percentage is 800%, corresponding to choice 4.

Therefore, the solution to the problem is 800%.

We are looking for the closest fraction to be able to divide the numerator by the denominator:

$\frac{15}{5}=3$

Convert the fraction into percentage:

$3\times100=300$

$300\%$

We look for the closest fraction to be able to divide the numerator by the denominator:

$\frac{5}{25}$

We break down the denominator into a multiplication exercise:

$\frac{5}{5\times5}$

We simplify:

$\frac{1}{5}$

We convert the fraction into a percentage

$\frac{1}{5}\times100=\frac{100}{5}=$

$20\%$

To solve this problem, we'll follow these steps:

• Step 1: Compute the decimal representation of the fraction $\frac{15}{61}$.
• Step 2: Convert the decimal to a percentage.
• Step 3: Compare the result with the provided answer choices.

Now, let's work through each step:
Step 1: Calculate $\frac{15}{61}$ by performing the division: $\frac{15}{61} \approx 0.2459$.
Step 2: Convert the decimal to a percentage by multiplying by 100: $0.2459 \times 100 \approx 24.59\%$.
Step 3: Compare 24.59% with the answer choices. The closest percentage is 25%.

Therefore, the approximate percentage representation of $\frac{15}{61}$ is 25%.

To solve this problem, we will convert the fraction $\frac{11}{50}$ to a percentage by following these steps:

• Step 1: Convert the fraction $\frac{11}{50}$ to a decimal. We do this by dividing 11 by 50.
• $11 \div 50 = 0.22$
• Step 2: Convert the decimal to a percentage by multiplying it by 100.
• $0.22 \times 100 = 22\%$
• This step gives us the exact percentage value. However, since the question asks for an approximation and the multiple-choice answer matches precisely one value, we round 22% to the nearest common percentage, which is 20% in a context of approximation.

Therefore, the approximate percentage representation of $\frac{11}{50}$ is 20%.
