Answer 2

$\huge\sf{\boxed{\orange{Answer:}}}$

(1) 28:44 & 42:66

L.H.S:

28:44

= $\frac{28}{44}$

= $\frac{7}{11}$

= 7:11

R.H.S:

42:66

= $\frac{42}{66}$

= $\frac{7}{11}$

= 7:11

Since, 28:44 = 7:11 & 42:66 = 7:11

These 2 ratios are equal.

(2) 48:78 & 91:56

L.H.S:

48:78

= $\frac{48}{78}$

= $\frac{8}{13}$

= 8:13

R.H.S

91:56

= $\frac{91}{56}$ (This fraction will remain the same as 91 is a prime no.)

= 91:56

Since, 48:78 = 8:13 & 91:56 = 91:56

These 2 ratios are not equal.
