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

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

salt=2u

sugar=7u

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

To find the amount of salt used by the chef, we need to calculate the ratio between salt and sugar and then use that ratio to find the amount of salt.

The given ratio of salt to sugar is 2:7. This means that for every 2 parts of salt, there are 7 parts of sugar.

We are told that the chef uses 129.5g of sugar. Let's calculate the amount of salt:

7 parts of sugar corresponds to 129.5g of sugar.
1 part of sugar corresponds to 129.5g / 7 = 18.5g of sugar.

Since the ratio of salt to sugar is 2:7, we can calculate the amount of salt:

2 parts of salt corresponds to 2 * 18.5g = 37g of salt.

Therefore, the chef uses 37g of salt.

To find out how much salt the chef uses, we'll use the given ratio of 2:7 and the known amount of sugar used (129.5g).

First, let's calculate the total parts of the ratio:
2 + 7 = 9

Next, we'll determine the value of one part:
Total amount of sugar / Ratio denominator = 129.5g / 7 = 18.5g

Now that we know the value of one part, let's find out how much salt the chef uses:
Salt = Value of one part * Ratio numerator
= 18.5g * 2
= 37g

Therefore, the chef uses 37g of salt to make the sauce.
