Question 1:

We have to find the LCD of and

LCD is the least common denominator is the lowest common multiple of the denominators of a set of fractions.

Here the denominators are 5 and 6.

So, we will find the LCM of 5 and 6

5 =

6 =

LCM of 5 and 6 =

= 30

Therefore, the LCD of these numbers is 30.

Question 2:

We have to find the difference between    and  .

Difference =

LCM of 7 and 14 is 14

Therefore, difference =

=

Question 3:

Amount of brown sugar used by Sandy =

Amount of sugar increased by Sandy =

Total amount of Sugar used by Sandy =

LCM of 3 and 9 is 9.

Total amount of Sugar used =

= cup

Question 4:

Let the number which should be added to to make the sum greater than be 'x'

So,

LCM of 2 and 15 is 30.

So, the number is

Question 5:

We have to identify the set of mixed numbers has a difference less than 1.

Set 1: and

Difference =

=

=

This set has difference less than 1.

Set 2:

and

Difference =

=

=

This set does'not have difference less than 1.

Set 3:

and

Difference =

=

=

=

This set does'not have difference less than 1.

Set 4:

and

Difference =

=

=

This set does'not have difference less than 1.
