Judy is playing a card game. She needs to select two cards below that have a sum greater

Zielflug [23.3K]

Answer:

$2\frac{2}{5} + 2\frac{5}{8} \simeq 5$

$2\frac{2}{7} + 2\frac{5}{8} \simeq 5$

Step-by-step explanation:

Mixed fraction $a\frac{b}{c}$ can be converted into like or unlike fractions.

Here, $a\frac{b}{c} = \frac{ac +b}{b}$

So, convert all the given fractions as follows:

$2\frac{2}{5} = \frac{2(5) +2}{5} = \frac{12}{5} =2.4$

$2\frac{2}{7} = \frac{2(7) +2}{7} = \frac{16}{7} =2.4$

$1\frac{7}{8} = \frac{1(8) +7}{8} = \frac{15}{8} =1.8$

$2\frac{1}{10} = \frac{2(10) + 1}{10} = \frac{21}{10} =2.1$

$2\frac{5}{8} = \frac{2(8) +5}{8} = \frac{21}{8} =2.6$

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

⇒ $2\frac{2}{5} + 2\frac{5}{8} \simeq 5$

or ⇒ $2\frac{2}{7} + 2\frac{5}{8} \simeq 5$
