Answer 1

Explicación paso a paso:

1) 0,75 kg + 2500 mg =

$0.75 \: kg \times \frac{1000 \: gr}{1kg} = \frac{0.75 \times 1000gr}{1} = 750gr$

$2500 \: mg \times \frac{1 \: mg}{1000} = \frac{2500 \times 1gr}{1000} = 2.5gr$

$750gr + 2.5gr \: = 752.5gr$

2) 42 dag + 3 hg

$42dag \: \times \frac{10gr}{1dag} = \frac{42 \times 10}{1} = 420 \:$
