D) 3 - (15 ÷ 6)

Answer 1

The correct expression to subtract 3 from 15 and then divide by 6 is represented by the expression (15 - 3) ÷ 6, which corresponds to option B.

Step-by-step explanation:

To represent the calculation "subtract 3 from 15 then divide by 6", we first need to perform the subtraction part. According to the order of operations, we subtract 3 from 15, which is represented as (15 - 3). After the subtraction is complete, we divide the result by 6. This operation can be represented mathematically as (15 - 3) ÷ 6.

The correct expression for the given calculation is therefore option B) (15 - 3) ÷ 6.
