`135.59÷7.62xx2.93=75.01%of?`

Options

A. 80
B. 68
C. 40
D. 20

Answer

To solve the equation \( 135.59 \div 7.62 \times 2.93 = 75.01\% \text{ of } ? \), we will approximate the values and find the value of the question mark step by step.

### Step 1: Approximate the values
- Approximate \( 135.59 \) to \( 136 \)
- Approximate \( 7.62 \) to \( 8 \)
- Approximate \( 2.93 \) to \( 3 \)

### Step 2: Rewrite the equation with approximations
The equation now looks like:
\[ \frac{136}{8} \times 3 = 75\% \text{ of } ? \]

### Step 3: Calculate \( \frac{136}{8} \)
- \( \frac{136}{8} = 17 \)

### Step 4: Multiply by \( 3 \)
Now, we multiply:
\[ 17 \times 3 = 51 \]

### Step 5: Rewrite the equation
Now, we have:
\[ 51 = 75\% \text{ of } ? \]

### Step 6: Convert percentage to decimal
Convert \( 75\% \) to a decimal:
\[ 75\% = \frac{75}{100} = 0.75 \]

### Step 7: Set up the equation for the question mark
Now we can express this as:
\[ 51 = 0.75 \times ? \]

### Step 8: Solve for \( ? \)
To find \( ? \), we rearrange the equation:
\[ ? = \frac{51}{0.75} \]

### Step 9: Simplify the division
Calculating \( \frac{51}{0.75} \):
\[ ? = 51 \div 0.75 = 51 \times \frac{100}{75} = 51 \times \frac{4}{3} = 68 \]

### Conclusion
Thus, the approximate value of \( ? \) is \( 68 \).
