Question

two jars measures 18 litre and 30 l respectively what is least measure that can be used to exactly measure each jar

Answer 1

This is a question that requires us to get the LCM of the two numbers

18 and 30

18 = 2 x 3 x 3

30 = 2 x 3 x 5

The LCM

= 2 x 3 x 3 x 5

= 90


90L can measure exactly each jar

Answer 2

Step-by-step explanation:

lcm of 18,30

18=2×3×3

30=2×5×3

LCM=2×3×3×5

=90

therefore 90 L can be measure exactly in each jar
