Question 1:
We have to find the LCD of
and ![\frac{1}{6}](/tpl/images/0078/1496/c8870.png)
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 =![5 \times 1](/tpl/images/0078/1496/f7d02.png)
6 =![2 \times 3](/tpl/images/0078/1496/37f40.png)
LCM of 5 and 6 =![2 \times 3 \times 5](/tpl/images/0078/1496/faecf.png)
= 30
Therefore, the LCD of these numbers is 30.
Question 2:
We have to find the difference between
and
.
Difference =![\frac{3}{7}- \frac{1}{14}](/tpl/images/0078/1496/843fd.png)
LCM of 7 and 14 is 14
Therefore, difference =![\frac{6-1}{14}](/tpl/images/0078/1496/b820a.png)
=![\frac{5}{14}](/tpl/images/0078/1496/9e79f.png)
Question 3:
Amount of brown sugar used by Sandy =![\frac{1}{3}](/tpl/images/0078/1496/5506e.png)
Amount of sugar increased by Sandy =![\frac{2}{9}](/tpl/images/0078/1496/746ea.png)
Total amount of Sugar used by Sandy =![\frac{1}{3}+\frac{2}{9}](/tpl/images/0078/1496/749b3.png)
LCM of 3 and 9 is 9.
Total amount of Sugar used =![\frac{3+2}{9}](/tpl/images/0078/1496/06be1.png)
=
cup
Question 4:
Let the number which should be added to
to make the sum greater than
be 'x'
So,![\frac{2}{15}+x \frac{1}{2}](/tpl/images/0078/1496/5023f.png)
LCM of 2 and 15 is 30.
So, the number is![\frac{11}{30}](/tpl/images/0078/1496/ef202.png)
Question 5:
We have to identify the set of mixed numbers has a difference less than 1.
Set 1:
and ![1 \frac{1}{9}](/tpl/images/0078/1496/ebaa5.png)
Difference =![1 \frac{2}{9}-1 \frac{1}{9}](/tpl/images/0078/1496/cc9de.png)
=![\frac{11}{9}- \frac{10}{9}](/tpl/images/0078/1496/d6747.png)
=![\frac{1}{9}](/tpl/images/0078/1496/f5492.png)
This set has difference less than 1.
Set 2:
Difference =![3 \frac{4}{7}-2 \frac{1}{7}](/tpl/images/0078/1496/85e72.png)
=![\frac{25}{7}- \frac{15}{7}](/tpl/images/0078/1496/c7771.png)
=![\frac{10}{7}](/tpl/images/0078/1496/7b755.png)
This set does'not have difference less than 1.
Set 3:
Difference =![2 \frac{4}{5}-1 \frac{1}{3}](/tpl/images/0078/1496/32e3e.png)
=![\frac{14}{5}- \frac{4}{3}](/tpl/images/0078/1496/544c1.png)
=![\frac{42-20}{15}](/tpl/images/0078/1496/00606.png)
=![\frac{22}{15}](/tpl/images/0078/1496/50b80.png)
This set does'not have difference less than 1.
Set 4:
Difference =![2 \frac{7}{9}-1 \frac{1}{3}](/tpl/images/0078/1496/ea092.png)
=![\frac{25}{9}- \frac{4}{3}](/tpl/images/0078/1496/6782a.png)
=![\frac{13}{9}](/tpl/images/0078/1496/9fad4.png)
This set does'not have difference less than 1.
