Answer:

220 by 750=22/75

820by1600=41/80

Answer 2

Answer:

Step-by-step explanation:

1) 220 = 2 * 2 * 5 * 11

750 =  2 * 5 * 5*5*3

HCF = 2 *5 = 10

The numerator and denominator by 10

$\dfrac{220}{750}=\dfrac{22}{75}$  

2) 820 = 2 * 2 * 5 * 41

1600 = 2 * 2 * 2 * 2 *  2 * 2 * 5 * 5

HCF = 2*2*5 = 20

The numerator and denominator by 20

$\dfrac{820}{1600}=\dfrac{41}{80}$
