Find a recipe in a book or online that includes the amount of salt as a fraction.Model how to find the amount of salt needed when the recipe is doubled

I will give you a example.

If you find a recipe with 1/3 tablespoon salt, it would be 1/3+1/3=2/3

Never change the bottom number (Denominator) unless the two denominators are diffrent.

in a card game,each player is dealt 5 cards.Make a table to show the total number of cards dealt for each number of players from 3 to 6.Write each ratio of players to cards dealt.

Answers

so since each player is dealt 5 cards
ratio of cards per player is 5:1

so if 3 players
5 times 3=15 cards

4 players=4 times 5=20 cards

5 players=5 times 5=25 cards

6 players=6 times 5=30 cards


ratio of cards per player is 5:1
since each palyer gets 5 cards each then 3 people is 15 cards & 4 people is 20 cards & 5 people is 25 cards and 6 people is 30 cards all together so there will be 30 cards all together 3:15                                                                                                                                      4:20                                                                                                                                      5:25                                                                                                                                          6:30  

How do you convert 0.65 into a fraction

Answers

so its 0.65 so make that 65. then make it 65 over 100 then find 65 and 100's gcf (greatest common factor) then divide until its fully reduced
0.65 is just like 65/100, all you gotta to do is turn 0.65 to a reg. number over a 100,hope that wasn't too confusing.

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yard peices can she cut and still have 1 1/4 yards left?

Answers

If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.

You estimate that there are 44 marbles in a jar. The actual amount is 73 marbles. Find the percent error.

Answers

Answer:

Percentage Error in counting the marbles in the jar is 39.72%

Step-by-step explanation:

Estimated marbles in the jar = 44

Actual marbles in the jar  = 73

Error in  Marbles  =  Number of actual Marbles - Estimated marbles

                                 =   73  - 44 = 29

So, the error in counting marbles in the jar is 29.

Now, \textrm{Percentage Error}  = \frac{\textrm{Error in the Data}}{\textrm{Actual Data}}  * 100

= (29)/(73)  * 100  = 39.72

or, Percentage Error  =  39.72%

Hence, the Percentage Error in counting the marbles in the jar is 39.72%
