Question

Express 35 ml as a percent of 7 litres

Answer 1

Hi ,

1 litre = 1000ml

Let x % of 7 litres = 35ml

x/100 × 7000ml = 35 ml

x = ( 35 × 100 ) / 7000

x = 1/2

Therefore ,

1/2% of 7 liters = 35ml

I hope this helps you.

:)

Answer 2

35ml = 0.035 liters
then
we assume % is a
then
(a x 7)/100 = 0.035
a =3.5 / 7 = 0.5 %
