Answer:
[D] 25 ÷ 5
Explanation:
In order to know which expression is equivalent to 25 × 1/5 we have to solve it and the answer choices given.
→ 25 × 1/5
→ 25/5
→ 5
As you can see the result is 5. Thus, we have to find a answer choice with the same answer.
Starting with [A] 1/25 × 5.
→ 1/25 × 5
→ 5/25
→ 1/5
5 ≠ 1/5
Thus, [A] 1/25 × 5 is wrong.
Next we have [B] 1/25 ÷ 1/5.
→1/25 ÷ 1/5
→1/25 × 1/5
→5/25
→1/5
5 ≠ 1/5
Thus, [B] 1/25 ÷ 1/5 is wrong.
Follow by [C] 5 ÷ 25.
→5 ÷ 25
→1/5
5 ≠ 1/5
Thus, [C] 5 ÷ 25 is wrong.
Finally we have [D] 25 ÷ 5.
→25 ÷ 5
→5
5 = 5
As a result, the expression that is equivalent to 25 × 1/5 is [D] 25 ÷ 5.
