Answer 1

Answer:

do lcm of denominators and plus the numerators

Answer 2

Answer:

(i) $\frac{18}{24}$ , $\frac{20}{24}$ , $\frac{21}{24}$ ; (ii) $\frac{56}{200}$ , $\frac{180}{200}$ , $\frac{95}{200}$

Step-by-step explanation:

(i) 3/4 , 5/6 , 7/8

LCD(4, 6, 8) = 24

(3×6) / (4×6) , (5×4) / 6×4) , (7×3) / (8×3)

18/24 , 20/24 , 21/24

$\frac{18}{24}$ , $\frac{20}{24}$ , $\frac{21}{24}$

(ii) 7/25 , 9/10 , 19/40

LCD(25, 10, 40) = 200

(7×8) / (25×8) , (9×20) / (10×20) , (19×5) / (40×5)

56/200 , 180/200 , 95/200

$\frac{56}{200}$ , $\frac{180}{200}$ , $\frac{95}{200}$
