?:−12⋅8=−24
\( ?:-12\cdot8=-24 \)
\( -6\cdot6:-3:?=24 \)
\( 20:?\cdot-4=-80 \)
\( -9\cdot-7:?=-3 \)
\( \frac{\text{?}}{-4}\cdot38:-9=-5 \)
Let's factor 24 into a multiplication exercise:
We'll simplify the 8 in both terms and get:
Let's multiply by negative 12:
We'll simplify between negative 12 and get:
Let's note that we are multiplying two negative numbers, so the result will necessarily be a positive number:
Let's write the exercise in the following form:
We'll factor the 6 in the numerator into a multiplication exercise:
We'll cancel out the minus 3 found in the numerator and denominator of the fraction and get:
We'll multiply the question mark:
We'll divide by 24:
We'll factor 24 into a multiplication exercise:
We'll cancel out the 12 in the numerator and denominator of the fraction:
