Question

Express the given ratios in their simplest forms:
$3$kg $750$g : $20$ kg

Answer 1

$3kg750g:20kg$

$1kg=1000g$

$\frac{1}{1000}kg=1g$

$750g=\frac{750}{1000}=0.75kg$

$3kg750g=3kg+0.75kg=3.75kg$

$3.75kg:20kg$

$=\frac{375}{100\times 20}=\frac{15}{4\times 20}=\frac{3}{16}$

$\therefore 3kg750g:20kg=3:16$
