I GIVE BRAINLILSET ......................,,,,,.,

Answer 1

${\bf \red {\huge{answer : }}}$

The money increased from 600 pounds to 621 pounds.

621 - 600 = 21

so , the money increased more 21 pounds.

$\pink {\sf{hence , \frac{21}{621} \times 100 }}$

$\red{= \frac{21}{\cancel{621}} \times \cancel{100 } }$

$\red{= \frac{21}{\cancel{6.21}} \times \cancel{1 } }$

$\red{= \frac{\cancel{21}}{\cancel{6.21}} }$

$\red{= \frac{3 \frac{79}{207} }{1} }$

$\red{= 3 \frac{79}{207} }$

Therefore , the dog's weight increased by 3 79/207%
