a chef uses salt and sugar in the ratio 2:7 to make a sauce.if the chef uses 129.5g of sugar,how much salt does he use? show ur answer clearly pls

Answer 1

amount of salt = 2x g
amount of sugar = 7x g , notice 2x:7x = 2:7

but 7x = 129.5
x = 18.5
then salt is 2x = 2(18.5) = 37 g

Answer 2

salt=2u
sugar=7u

7u=133g
1u=133 divide by 7=19
2u=19 multiply by 2=38
