A 208-yard-long road is divided into 16 parts of equal length. Mr. Ward paints a 4-yard-long strip in each part. How long is the
laila [671]

We have been given that a 208-yard-long road is divided into 16 parts of equal length.

Let us find length of each part.

\text{Length of each part}=\frac{208}{16}

\text{Length of each part}=13

Length of each part will be 13 yards.                

We are told that Mr. Ward paints a 4-yard-long strip in each part.

Now we will subtract length of painted strip from length of each equal part to find length of unpainted strip of each part of the road.

\text{Length of unpainted strip}=13-4

\text{Length of unpainted strip}=9    

Therefore, length of each unpainted strip will be 9 yards.

How many 1/3 cup servings of juice are in a 5 cup container
vesna_86 [32]

Answer:

We can get 15  (1/3 cup) servings with a 5 cup container

Step-by-step explanation:

To solve this problem, we can easily divide 5 by (1/3)  to find how many servings can be obtained

5 /  (1/3)  

=  5 / (0.3333)

= 15

This can be checked by adding together (1/3) fifteen times

(1/3) + (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)

= 15/3  = 5

Dmitrij [34]
For this case we can make the following rule of three:
 1 cup ----------------> 128 grams
 x ----------------------> 192 grams
 From here, we clear the value of x.
 We have then:
 x = (192/128) * (1)
 x = 1.5
 x = 1 1/2
 Answer:
 
She needs about 1 1/2 cups.
