Answer:
[tex]2\frac{2}{5} + 2\frac{5}{8} \simeq 5[/tex]
[tex]2\frac{2}{7} + 2\frac{5}{8} \simeq 5[/tex]
Step-by-step explanation:
Mixed fraction [tex]a\frac{b}{c}[/tex] can be converted into like or unlike fractions.
Here, [tex]a\frac{b}{c} = \frac{ac +b}{b}[/tex]
So, convert all the given fractions as follows:
[tex]2\frac{2}{5} = \frac{2(5) +2}{5} = \frac{12}{5} =2.4[/tex]
[tex]2\frac{2}{7} = \frac{2(7) +2}{7} = \frac{16}{7} =2.4[/tex]
[tex]1\frac{7}{8} = \frac{1(8) +7}{8} = \frac{15}{8} =1.8[/tex]
[tex]2\frac{1}{10} = \frac{2(10) + 1}{10} = \frac{21}{10} =2.1[/tex]
[tex]2\frac{5}{8} = \frac{2(8) +5}{8} = \frac{21}{8} =2.6[/tex]
Here, No Two fractions on addition gives a sum greater than 5.
But an approximate sum of 5 is given by adding 2.4 + 2.6 = 5
⇒[tex]2\frac{2}{5} + 2\frac{5}{8} \simeq 5[/tex]
or ⇒[tex]2\frac{2}{7} + 2\frac{5}{8} \simeq 5[/tex]
