Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa c

FromTheMoon [43]

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is $2\frac{1}{2}$ batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = $\frac{5}{6} \div \frac{1}{3}$

x = $\frac{5}{6} \times \frac{3}{1}$

x = $\frac{15}{6}$

x = $\frac{5}{2}$

x = $2\frac{1}{2}$

Hence, the number of batches Ben can make with 5/6 cup of green chilies is $2\frac{1}{2}$ batches of salsa.
