Division with Multiplication in Parentheses Practice Problems

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

• Step 1: Calculate the sum inside the parentheses.
• Step 2: Subtract the result of the sum from 100.

Now, let's work through each step:
Step 1: Calculate $5 + 55$, which gives $60$.
Step 2: Perform the subtraction $100 - 60$, which equals $40$.

Therefore, the solution to the problem is $40$.

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

• Step 1: Calculate the product of $14$ and $5$.
• Step 2: Use this product to divide $70$.
• Step 3: Compare the calculated result with the given choices.

Now, let's work through each step:
Step 1: First, calculate the product of $14$ and $5$. Using basic multiplication:
$14 \times 5 = 70$ Step 2: Divide $70$ by the product, which is also $70$:
$70 \div 70 = 1$

Therefore, the solution to the problem is $1$. This matches choice 1 from the provided options.

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

• Step 1: Compute the product $5 \times 6$.
• Step 2: Perform the division operation $300 \div 30$.

Now, let's work through each step:

Step 1: Calculate $5 \times 6$.

$5 \times 6 = 30$

Step 2: Divide 300 by the result from Step 1.

$300 \div 30 = 10$

Therefore, the solution to the problem is $\boxed{10}$.

This matches the choice: 10.

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

• Step 1: Evaluate the inner expression $6 - 13$
• Step 2: Substitute the result from Step 1 into $21 - \text{result from Step 1}$

Now, let's work through each step:

Step 1: Calculate $6 - 13$. In this calculation, we subtract 13 from 6. The result is $-7$, because when subtracting a larger number from a smaller one, the result is negative.

Step 2: Substitute $-7$ into the outer expression $21 - (-7)$. Since subtracting a negative is equivalent to adding the positive opposite, this simplifies to $21 + 7$.

Now, compute $21 + 7$, which equals 28.

Therefore, the solution to the problem is $28$.

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

• Step 1: Perform the inner division operation.
• Step 2: Use the result of Step 1 in the outer division operation.

Now, let's work through each step:

Step 1: Calculate $33:10$.
This operation is equivalent to dividing 33 by 10, which gives us:
$\frac{33}{10} = 3.3$.

Step 2: Use the result from Step 1 to perform the division $99:3.3$.
This operation now becomes:
$\frac{99}{3.3} = 30$.

Therefore, the solution to the problem is $30$.
