Answer:
LCD=280
Step-by-step explanation:
Equivalent Fractions with the LCD
1/8 = 35/280
2/7 = 80/280
4/5 = 224/280
Solution:
Rewriting input as fractions if necessary: 1/8, 2/7, 4/5
For the denominators (8, 7, 5) the least common multiple (LCM) is 280.
LCM(8, 7, 5)
Therefore, the least common denominator (LCD) is 280.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/8 = 1/8 × 35/35 = 35/280
2/7 = 2/7 × 40/40 = 80/280
4/5 = 4/5 × 56/56 = 224/280
What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?
