-3 1/2 as a Decimal
This is a straightforward question about decimal conversion. First, we need to understand fractions and decimals. A fraction represents a part of a whole, consisting of a numerator (the top number) and a denominator (the bottom number). In a mixed number like -3 1/2, we have a whole number (-3) and a fraction (1/2). A decimal represents a number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
