forsale [732]

Debnil have 2 tablespoons to salt.

Step-by-step explanation:

Given,

Number of teaspoons of salt = 6

Ratio of teaspoons to tablespoons = 3:1

Let,

x be the number of tablespoon of salt for 6 teaspoons.

Ratio of teaspoons to tablespoons = 6:x

Using proportion

Ratio of teaspoons to tablespoons :: Ratio of teaspoons to tablespoons

$3:1::6:x$

Product of mean = Product of extreme

$6*1=3*x\\6=3x\\3x=6$

Dividing both sides by 3

$\frac{3x}{3}=\frac{6}{3}\\x=2$

Debnil have 2 tablespoons to salt.
