Answer:

False

True

False

False

Step-by-step explanation:

1. We have to get the sum as follows :

[tex]3\frac{4}{9} + 4\frac{6}{9}[/tex]

= [tex]\frac{31}{9} + \frac{42}{9}[/tex]

= [tex]\frac{31 + 42}{9}[/tex]

= [tex]\frac{73}{9}[/tex]

= [tex]8\frac{1}{9} \neq 7\frac{1}{9}[/tex]

So, this is false.

2. We have to get the sum as follows :

[tex]4\frac{5}{6} + 1\frac{3}{6}[/tex]

= [tex]\frac{29}{6} + \frac{9}{6}[/tex]

= [tex]\frac{29 + 9}{6}[/tex]

= [tex]\frac{38}{6}[/tex]

= [tex]6\frac{2}{6}[/tex]

So, this is true.

3. We have to get the difference as follows :

[tex]4\frac{5}{8} - 2\frac{4}{8}[/tex]

= [tex]\frac{37}{8} - \frac{20}{8}[/tex]

= [tex]\frac{37 - 20}{8}[/tex]

= [tex]\frac{17}{8}[/tex]

= [tex]2\frac{1}{8} \neq 2\frac{3}{8}[/tex]

So, this is false.

4. We have to get the difference as follows :

[tex]7\frac{5}{8} - 4\frac{2}{8}[/tex]

= [tex]\frac{61}{8} - \frac{34}{8}[/tex]

= [tex]\frac{61 - 34}{8}[/tex]

= [tex]\frac{27}{8}[/tex]

= [tex]3\frac{3}{8} \neq 3[/tex]

So, this is also false. (Answer)
