Answer 2

Answer:

$\Huge\mathbb\purple{HELLO\; \:MATE}$

●We'll use HCF method and find common factors of digits(of ratios) and then we'll divide them by their common factors, and after that we'll find their lowest/simplest form.

$\Large{\fcolorbox{red}{blue}{\fcolorbox{red}{blue}{Here\:We\:Go⤵}}}$

1. 117:65

➡13 is common factor of 117 and 65.

= (117/13) / (65/13)

=9/5

=9:5

Thus, lowest form of 117:65 is 9:5.

2. 102:221

➡17 is the common factor of 102 and 221

=(102/17) / (221/17)

=6/13

=6:13

Thus,simplest form of 102:221 is 6:13.

3. 589:651

➡Common factor of 589 and 651 is 31.

=(589/31) / (651/31)

=19/20

=19:20

Thus,simplest form of 589:651 is 19:20.
