b. 96,66
C. 120, 108​

Answer 1

Answer:

Find least common multiple (L.C.M) of 20 and 30 by division method.

Solution:

least common multiple (L.C.M) of 20 and 30

Least common multiple (L.C.M) of 20 and 30 = 2 × 2 × 5 × 3 = 60.

2. Find least common multiple (L.C.M) of 50 and 75 by division method.

Solution:

Least Common Multiple (L.C.M) of 50 and 75

Least common multiple (L.C.M) of 50 and 75 = 5× 5 × 2 × 3 = 150.
