Answer:

7.87 inches.

Step-by-step explanation:

We are asked to convert 20 centimeters into inches.

We know that 1 inch equals 2.54 centimeters.

To convert 20 centimeters into inches, we will divide 20 by 2.54 as:

$\text{20 inches}=\frac{20}{2.54}\text{ inch}$

$\text{20 inches}=7.874\text{ inch}$

$\text{20 inches}\approx 7.87\text{ inch}$

Therefore 20 inches are equal to 7.87 inches.

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.
