B.6
C4
D1.25
Answer:
A. 2.1
Read Explanation:
Here's how to find the LCM of 1.05 and 2.1:
1. Convert Decimals to Fractions:
1.05 = 105/100 = 21/20
2.1 = 21/10
2. Find the LCM of the Numerators:
The numerators are 21 and 21.
The LCM of 21 and 21 is 21.
3. Find the HCF (GCD) of the Denominators:
The denominators are 20 and 10.
The HCF of 20 and 10 is 10.
4. Apply the Formula for LCM of Fractions:
LCM of fractions = LCM of numerators / HCF of denominators
LCM of 21/20 and 21/10 = 21 / 10 = 2.1
Therefore, the LCM of 1.05 and 2.1 is 2.1
