Answer:
2 & 4
Step-by-step explanation:
<em><u>1)</u></em><em> </em><em><u>-6(-4)(-1):</u></em>
This one you would multiply one at a time. So -6 * -4 is -24 but then you multiply it by -1 so the answer is 24.
<em><u>2)</u></em><em> </em><em><u>-1(-1)(-1)(24):</u></em>
Same thing one at a time. -1 * -1 is 1 then 1 *-1 is -1 and now we multiply it by 24 which is -24. This one is correct.
<em><u>3)</u></em><em> </em><em><u>24 divided by 1:</u></em>
This one is simple 24 divided by 1 will still be 24 which is not what we want.
<em><u>4)</u></em><em> </em><em><u>-240 divided by 10:</u></em>
This one is pretty much the same. -240 divided by 10 is -24. So this one is also correct.
<em><u>5)</u></em><em> </em><em><u>-8(3)(-1):</u></em>
This one is like the first ones, one step at a time. -8 * 3 is -24 then times -24 and -1 which is 24. This is false.
<em><u>6)</u></em><em> </em><em><u>-2(-12):</u></em>
This one is simple, -2 * -12 is 24 but it's not what we want so it's false.
