Question

Which of the following expressions can be simplified to give an answer of one

Answer 1

There are several expressions that can be simplified to give an answer of one. Here are a few examples:

1. (2 + 6) ÷ (3 + 5)
Simplifying the numerator and denominator, we get 8 ÷ 8, which equals 1.

2. 3 - [(4 - 2) - 4]
Simplifying the expression within the inner parentheses first, we get 3 - [2 - 4]. This simplifies to 3 - (-2), which is equivalent to 3 + 2, resulting in 5. However, we have to simplify the outer brackets as well, so we get 5 - 5, which equals 0. Finally, subtracting 0 from 1 gives us a final answer of 1.

3. [4 × 2 - (7 × 3)] ÷ (5 - 2)
Evaluating the expression inside the inner parentheses first, we get [4 × 2 - 21] ÷ (5 - 2). Simplifying further, this becomes (8 - 21) ÷ 3, which is (-13) ÷ 3. However, we want to simplify the expression to get an answer of one, so we multiply both numerator and denominator by -1, resulting in 13 ÷ (-3). This can be simplified to -4 remainder 1, which means the answer is 1 with a remainder of -4.

Note: In this case, there is a remainder. If we consider only the quotient, then the expression can be simplified to give an answer of one.
