Eli is making guacamole. he uses 2 tablespoons of cilantro for every 3 avocados. at this rate, how many tablespoons of cilantro will he need for 9 avocados?

6

Step-by-step explanation:

Write and solve an equation of proportions:

 cilantro             avocados

      2                          3

       x                          9

The appropriate equation is thus:

 2         3

=

  x         9

After cross-multiplication, we have 3x = 18, or x =  6.

Need 6 tablespoons of cilantro for 9 avocados.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
