6 - 1/4 * 28 - 2 1/4 _____ 3/4 + 4 * 2 - 11 which operation can be placed in the blank to make the statement true? >_

1 answer

To determine which operation can be placed in the blank to make the statement true, we first need to simplify both sides of the equation.

Let's simplify the left side:

  1. Calculate \( 6 - \frac{1}{4} \times 28 - 2\frac{1}{4} \):
    • \( \frac{1}{4} \times 28 = 7 \)
    • Now substitute back: \( 6 - 7 - 2\frac{1}{4} \)
    • Convert \( 2\frac{1}{4} \) to an improper fraction: \( 2\frac{1}{4} = \frac{9}{4} \).
    • So we have \( 6 - 7 - \frac{9}{4} \).

To simplify further, convert 6 and 7 to fractions over 4:

  • \( 6 = \frac{24}{4} \)
  • \( 7 = \frac{28}{4} \)

Thus, the left side simplifies to: \[ \frac{24}{4} - \frac{28}{4} - \frac{9}{4} = \frac{24 - 28 - 9}{4} = \frac{-13}{4} \]

Next, simplify the right side: \[ \frac{3}{4} + 4 \times 2 - 11 \] Calculating \( 4 \times 2 = 8 \), so we substitute to get: \[ \frac{3}{4} + 8 - 11 = \frac{3}{4} + 8 - 11 = \frac{3}{4} - 3 \] Convert -3 to a fraction: \[ -3 = -\frac{12}{4} \] Thus, we have: \[ \frac{3}{4} - \frac{12}{4} = \frac{3 - 12}{4} = \frac{-9}{4} \]

Now we have the simplified left and right sides: Left side: \(\frac{-13}{4}\) \ Right side: \(\frac{-9}{4}\)

Now, we can fill in the blank: \[ \frac{-13}{4} __ \frac{-9}{4} \] To find the correct operation for the blank: \[ \frac{-13}{4} < \frac{-9}{4} \] This means that the operation that can be placed in the blank to make the statement true is <.

Thus, the complete statement is: \[ 6 - \frac{1}{4} \times 28 - 2\frac{1}{4} < \frac{3}{4} + 4 \times 2 - 11 \]
