.75 or 75%

If there’s 20 kids total in the class and 15 out of the 20 are boys then you would divide the 15 by 20 and get .75 if you were doing it for girls then you would divide 5 by 20 and you would get .25 or 25%

Dani uses the table to help her convert measurements when she is sewing
Aleks [24]
The first thing we should do is see what relationship we have:
 Table is feet to yards 3-1
 a. Describe the relationship between the number of feet and the number of yards
 That is to say:
 1Yarda = 3 feet
 b. Write an expression for the number of yards in f feet
 Let
 y = Yard
 f = feet
 We have the following expression for the conversion:
 y = (1/3) f
 c. Find the number of yards in 63 feet 
 For this case we must substitute in the expression found the value of f = 63.
 y = (1/3) f
 y = (1/3) (63)
 y = 21
 answer:
 1Yarda = 3 feet
 y = (1/3) f
 y = 21

Josh's chicken soup recipe calls for 2 1 / 2 L of chicken stock. Josh makes 3 1 / 4 times the recipe for a family reunion. How m
Nataly_w [17]

Required amount of chicken stock = 2\frac{1}{2} = \frac{5}{2}L

Total amount of extra recipe made = 3\frac{1}{4}=\frac{13}{4}L

Total amount of chicken made is =  \frac{13}{4} * \frac{5}{2}= \frac{65}{8}L

Hence Josh made total \frac{65}{8} L of chicken soup.

Converting it to mixed fraction we get,

8\frac{1}{8} L

Whats 1 and 2/3 + 1 and 5/6​
Dima020 [189]
1 2/3 + 1 5/6

We’ll start by converting the 2/3 to 6ths so we have a common denominator.

Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.

So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.

Let me know where you have questions.
