Answer 2

$To \: convert \: a \: fraction \: into \: percent,$

$We \: have \: to \: multiply \: it \: with \: 100$

$1) \: \: 1:2 = 50%$

$\: \: 1:2 = \frac{1}{2} \times 100 = 50$

$2) \: \: 7:10 = 70%$

$\: \: 7:10 = \frac{7}{10} \times 100 = 70$

$3) \: 21:25 = 84%$

$\: \: 21:25 = \frac{21}{25} \times 100 = 84$

$4) \: 5:12 = 41% (approx.)$

$\: \: 5:12 = \frac{5}{12} \times 100 = 41.666.......$

$Have \: a \: good \: day \: ahead :) \:$
