Farid uses 8 fluid ounces of lemon juice in one batch of lemonade. How many batches can he

Sergio039 [100]

Answer:

He can make 2 batches of lemonade with 1 pint of lemon juice.

Step-by-step explanation:

First convert 1 pint to ounces

1 pint of lemon juice = 16 fluid ounces

To get the number of batches that can be made with 1 pint (16 fluid ounces) of lemon juice, we can simply use proportion;

Let x be the number of batches Farid can make with 1 pint(16 fluid ounces) of lemon juice

8 fluid ounces = 1 batch

16 fluid ounces = x

cross-multiply

8x = 16

Divide both-side of the equation by 8

8x/8 = 16/8

x= 2 batches.

Therefore, he can make 2 batches of lemonade with 1 pint of lemon juice.

Round to the nearest 10.

bearhunter [10]

Any picture? Example: if the number is 36 you would round to 40 and if the number was 34 you would round to 30 if it is 35 you choose what to round to. It depends on the last digit.
