Number Decomposition: Breaking Down 57.5 into Its Components

To solve this problem, we will decompose the number 57.5 by identifying the place value of each digit:

• First, note that the '5' in 57.5 is in the tens place, representing $5 \times 10 = 50$.
• The '7' is in the ones place, contributing $7 \times 1 = 7$.
• The '.5' is in the tenths place, which corresponds to $0.5$.

By adding these components together, we have:

$50 + 7 + 0.5$.

Thus, the decomposition of 57.5 is $50+7+0.5$.
