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

Answer:
= 15x +30y -220
Step-by-step explanation:
We can easily get another expression if we multiply each individual term, and
add together the result
30(1/2x-2)+40(3/4y-4)
= 15x-60 +30y-160
= 15x +30y -220
