The correct Answer is:
To solve the expression \( 4 \frac{1}{4} + 2 \frac{1}{4} \div \frac{3}{4} \times 4 \frac{2}{3} = ? \), we will follow the order of operations (BODMAS/BIDMAS). ### Step 1: Convert mixed numbers to improper fractions - Convert \( 4 \frac{1}{4} \) to an improper fraction: \[ 4 \frac{1}{4} = \frac{4 \times 4 + 1}{4} = \frac{16 + 1}{4} = \frac{17}{4} \] - Convert \( 2 \frac{1}{4} \) to an improper fraction: \[ 2 \frac{1}{4} = \frac{2 \times 4 + 1}{4} = \frac{8 + 1}{4} = \frac{9}{4} \] - Convert \( 4 \frac{2}{3} \) to an improper fraction: \[ 4 \frac{2}{3} = \frac{4 \times 3 + 2}{3} = \frac{12 + 2}{3} = \frac{14}{3} \] ### Step 2: Substitute the improper fractions back into the expression Now, the expression becomes: \[ \frac{17}{4} + \frac{9}{4} \div \frac{3}{4} \times \frac{14}{3} \] ### Step 3: Perform the division - Dividing \( \frac{9}{4} \) by \( \frac{3}{4} \): \[ \frac{9}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = \frac{9 \times 4}{4 \times 3} = \frac{9}{3} = 3 \] ### Step 4: Substitute back into the expression Now the expression is: \[ \frac{17}{4} + 3 \times \frac{14}{3} \] ### Step 5: Perform the multiplication - Multiply \( 3 \) by \( \frac{14}{3} \): \[ 3 \times \frac{14}{3} = \frac{3 \times 14}{3} = 14 \] ### Step 6: Substitute back into the expression Now the expression is: \[ \frac{17}{4} + 14 \] ### Step 7: Convert 14 to a fraction with a common denominator Convert \( 14 \) to a fraction with a denominator of 4: \[ 14 = \frac{14 \times 4}{4} = \frac{56}{4} \] ### Step 8: Add the fractions Now we can add: \[ \frac{17}{4} + \frac{56}{4} = \frac{17 + 56}{4} = \frac{73}{4} \] ### Final Answer Thus, the value that comes in place of the question mark is: \[ \frac{73}{4} \] ---
