To make 6 glasses of lemonade, Karla uses 1/2 cup of sugar, 1/2 cup of lemon juice, and 51/2 cup of water. If Karla wants to make 10 glasses of lemonade, which proportion can she use to determine how many cups of water, w, she will need?

Answers

Answer 1

Answer: lemonade sugar. lemon juice water

6 glasses...........1/2.................1/2................51/2
10 glasses.........x.....................y...................z

x=(10*1/2)/6
x=10/2/6
x=5/6 sugar

y=x=5/6 lemon juice

z=(51/2*10)/6
z=(510/2)/6
z=255/6 water

How do you write the fraction 7/10 as a sum of fractions three different ways

Answers

First three sum1/10 + 2/10 + 4/10Proof: When the numbers in the denominator have the same value, fractions can be compute only with the sum of numerator values and the denominator doesn’t change.1/10 + 2/10 + 4/10 = 1+2+4 / 10 = 7/10Second three sum1/10+1/5 + 2/5,Proof: such kind of fractions can be computed as follows: 1/10 + (1+2 )/5 (same denominators). 1/10 + (1+2 )/5= 1/10 + 3/5= 5x1 +10x3 / 5x10 = 5+30 /50 =35/50, by simplifying by 5, 35/50=7/10The third three sum is5/10+ 3/15+8/20,it can be computed by using the same method as given above

Final answer:

To write the fraction 7/10 as a sum of fractions three different ways, you can use a common denominator, multiples of the denominator, or equivalent fractions.

Explanation:

To write the fraction 7/10 as a sum of fractions three different ways, we can use different denominators. Here are three ways:

Using a common denominator: Multiply the numerator and denominator of 7/10 by 3/3 to get 21/30. Then, express 21/30 as the sum of three fractions with different numerators: 7/30 + 7/30 + 7/30.
Using multiples of the denominator: Express 7/10 as the sum of fractions with denominators that are multiples of 10, such as 20, 30, and 40. So, 7/10 can be written as 14/20 + 21/30 + 28/40.
Using equivalent fractions: Find equivalent fractions of 7/10 with different denominators, such as 14/20, 21/30, and 28/40. Then, express 7/10 as the sum of these equivalent fractions.

Write 5/10 in three equivalent forms

Answers

equivalent fractions are fractions which have the same value.

equivalent fractions all have the same simplified form

we can write equivalent fractions by multiplying both numerator and denominator by the same number. We can also write equivalent fractions by dividing both numerator and denominator by the same number

so 5/10

we can get the equivalent fractions by multiplying by a common number

when we multiply by 2

$(5)/(10)* 2= (5*2)/(10*2) = (10)/(20)$

when we multiply by 3

$(5)/(10)* 3 = (5*3)/(10*3) = (15)/(30)$

when we multiply by 4

$(5)/(10) *4 = (5*4)/(10*4) = (20)/(40)$

the three equivalent fractions are

10/20 , 15/30, 20/40

Some Equivalent Forms include:

0.5

10/20

50/100

Perry surveyed 60 students at her school and found that 0.45 of the students she surveyed said their favorite class is math. Another 35% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?

Answers

1. Perry surveyed 60 students at her school.
=> 0.45 of the students said that their favorite subject is math
=> 0.45 x 100 = 45%
Thus, 45 % of 60:
=> 60 * .45 = 27
35% of the student said their favorite is science:
=> 35% / 100 = 0.35
=> 35% 0f 60 equals:
=> 60 * .35 = 21
Thus, 27 – 21 = 6 of the student said that they love math over science.

the post office sold 900 stamps yesterday.1/4 of the stamps are postcard stamps. How many postcard stamps did they sell?

Answers

1/4 = .25 or 25%
a(postcard stamps) = .25(percentage of postcard stamps) * 900(total of stamps)
900 * .25 = 225
They sold 225 postcard stamps

To check:
225 * 4 = 900

Hello! To solve this problem you can convert 1/4 into a decimal (0.25), and then multiply that decimal by 900. You multiply the two because 25% (1/4) percent of the stamps are postcard stamps, thus by doing so you're able to determine how many of the stamps were postcard stamps. You should get an answer of 225 stamps.
