lorasvet [3.4K]

Answer:

Second option

Step-by-step explanation:

We will use the process of elimination to find the answer:

<u>First option:</u>
4+(8\times4)\div6+7
8\times4=32
4+32\div6+7
4+32=36
36\div6+7
36\div6=6
6+7=13
=13

<u>Second option:</u>
(4+8)\times4\div6+7
4+8=12
12\times4\div6+7
12\times4=48
48\div6+7
48\div6=8
8+7=15
=15

Which means your answer is the second option or "4 + (8 × 4) ÷ 6 + 7."

Hope this helps.
