Question

Which expressions are equal to 0.15?

A. 5 × 13/10
B. 5 x 0.03
C. 1/1/06 × 1/1/0
D. 0.05 × 3
E. 0.05 × 0.03

Answer 1

Expressions B (5 x 0.03) and D (0.05 x 3) both equal 0.15. Options A, C, and E do not simplify to 0.15.

Step-by-step explanation:

The student has asked which expressions are equal to 0.15. We check each option by simplifying or performing the operations:

• Option B: 5 x 0.03 = 0.15 (This is one correct answer)
• Option D: 0.05 x 3 = 0.15 (This is another correct answer)

Options A, C, and E do not simplify to 0.15. When approaching these types of problems, it's essential to understand basic operations with fractions, decimals, and multiples as well as conversion between units if necessary. For example, knowing that the relative frequency of 15/100 is equal to 0.15 can provide a quick check to evaluate whether the expression simplifies to the desired value.
