    Answer:

    The correct answer is: [tex]4\frac{3}{5}[/tex]

    Step-by-step explanation:

    According to the rule of BODMAS, division is done before addition.

    So, in a + b ÷ c, we will first calculate,  b ÷ c

    Given b =  [tex]2\frac{2}{5}[/tex] = [tex]\frac{12}{5}[/tex] , c = [tex]\frac{3}{4}[/tex] .

    So, [tex]\frac{b}{c}[/tex] = [tex]\frac{12}{5}[/tex] ÷ [tex]\frac{3}{4}[/tex]

    So, [tex]\frac{b}{c} = \frac{12}{5} \times\frac{4}{3}[/tex] , as the numerator and denominator gets reversed as division is changed to multiplication.

    So, [tex]\frac{b}{c} = \frac{16}{5}[/tex] .

    Next the value of a to  [tex]\frac{b}{c}[/tex]  , where, [tex]a = 1\frac{2}{5} = \frac{7}{5}[/tex], we get,

    [tex]\frac{7}{5} +\frac{16}{5} = \frac{23}{5} = 4\frac{3}{5}[/tex].
