Question 1

Evaluate:........

(3)/(4) + (5)/(6) + (7)/(8)

Question 2

Answer:

$\large \rm (3)/(4) + (5)/(6) + (7)/(8)$

$\large \rm (3)/(4) = (3 * 6)/(4 * 6) = (18)/(24)$

$\large(5)/(6) = (5 * 4)/(6 * 4) = (20)/(24)$

$\large (7)/(8) = (7 * 3)/(8 * 3) = (21)/(24) =(59)/(24)=2(11)/(24)$

Question 3

$\dashrightarrow(3)/(4) + (5)/(6) + (7)/(8) \\ \\$

$\\ \\$

$\sf \dashrightarrow \frac{(3 * 24)/(4) + (5 * 24)/(6) + (7 *24)/(8)} {24} \\ \\$

$\\ \\$

$\sf \dashrightarrow \frac{3 * 6 +5 * 4+ 7 * 3} {24} \\ \\$

$\\ \\$

$\sf \dashrightarrow \frac{18 +20+ 21} {24} \\ \\$

$\\ \\$

$\sf \dashrightarrow \frac{18 +41} {24} \\ \\$

$\\ \\$

$\sf \dashrightarrow \frac{59} {24} \\ \\$

$\\ \\$

$\sf \dashrightarrow 2.4 \\ \\$

$\\ \\$
