Question

1. a scuba diver swims to a depth of 10\frac{15}{20} meters below sea level. part a: write the decimal equivalent to - 10\frac{15}{20}. a) - 10.15 b) - 10.5 c) - 10.\overline{15} d) - 10.75 part b: the decimal is repeating/terminating (circle one)

Explanation:

Step1: Convert the fraction part to decimal

First, convert $\frac{15}{20}$ to decimal. Divide 15 by 20: $15\div20 = 0.75$.

Step2: Combine with the whole - number part

The number is $- 10\frac{15}{20}$, so it is $-10 - 0.75=-10.75$.

Step3: Determine the type of decimal

Since $-10.75$ has a finite number of digits after the decimal point, it is a terminating decimal.

Answer:

Part A: D. - 10.75
Part B: terminating
