Solve the equation using equivalent fractions. show your work.

Answer 1

3 3/10

-

to find the answer to the equation, you need to find the least common denominator (LCD) of the three fractions:

15: 15, 30, 45, 60, 75

10: 10, 20, 30, 40, 50, 60

5: 5, 10, 15, 20, 25, 30

in this problem, the LCD is 30.

then, multiply the numerator by the number you found the LCD with:

⁶⁄₁₅ = ¹²⁄₃₀, ³⁄₁₀ = ⁹⁄₃₀, and ⅗ = ¹⁸⁄₃₀.

¹²⁄₃₀ + ⁹⁄₃₀ + ¹⁸⁄₃₀ = 3 ⁹⁄₃₀ = 3 ³⁄₁₀ when simplified.
