Answer:
im guessing you wanted me tho find the common denominator of 7 8/10 and 1 1/4 the LCD would be 20.
Step-by-step explanation:
Solution:
Rewriting input as fractions if necessary:
78/10, 5/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
78/10 = 78/10 × 2/2 = 156/20
5/4 = 5/4 × 5/5 = 25/20
