Express 2/5/7 as a decimal, correct to 1 decimal place.
To express the fraction 2/5/7 as a decimal, we first need to solve the expression correctly. The expression is a bit ambiguous because it could be interpreted in two ways:
1. (2/5)/7
2. 2/(5/7)
For both interpretations, we'll need to solve the fraction step by step, and we'll convert the result to a decimal correct to one decimal place.
Interpretation 1: (2/5)/7
First, we calculate 2/5:
2 ÷ 5 = 0.4
Then we divide the result by 7:
0.4 ÷ 7 ≈ 0.0571428571...
To one decimal place, this is approximately 0.1.
Interpretation 2: 2/(5/7)
First, we calculate 5/7:
5 ÷ 7 ≈ 0.7142857142...
Then we divide 2 by the result:
2 ÷ (5/7) ≈ 2 ÷ 0.7142857142
≈ 2.8 (rounded to one decimal place)
So, the decimal representation of 2/5/7 would be 0.1 or 2.8, depending on how the original expression was meant to be interpreted. However, without parentheses to clarify the order of operations, the expression is ambiguous.
