Krish has only 2 cups of diced pumpkins, when he needs 3. How many tablespoons of sugar must he use to keep the same proportions?

Answer 1

and sugar is 1 1/4 tablespoons

Answer 2

@KingGeorge @phi @e.mccormick

Answer 3

is it 5/6?

Answer 4

So the original proportion is 2 cups of diced pumpkins to 1.25 tablespoons correct?

Answer 5

yes

Answer 6

you need ⅔ of the original amount of sugar

Answer 7

So that tells you that\[\frac{2}{1.25}=\frac{3}{x}\]where \(x\) is how many tablespoons you need for 3 cups of diced pumpkins.

Answer 8

the original ratio was 3 / 1.25

Answer 9

All you need to do from there, is solve for \(x\). Can you do that on your own?

Answer 10

can i just simply multiply 1.25/1 * 2/3= 2.5/3 = 5/6

Answer 11

yes 2.5/3 is 5/6, which is correct.

Answer 12

okay can you please help me on my second problem please?

Answer 13

When Krish took the Saag Kumro to his friends, his friends start to savor the taste of the dish. Soon enough, Krish noticed that his friends had sent the news about how great the food was, to their friends. So 4 more people ask Krish to make the Saag Kumro with the same proportions of ingredients. Two want 1/2 of the dish, and the other two each want a whole bowl. How many more tablespoons of sugar does he need?

Answer 14

I don't think 5/6 is correct...

Answer 15

i got the fact that i have to multiply 5/6*3 (since there is 3 cakes)

Answer 16

Oh. I read the problem wrong...oops.

Answer 17

King, the problem says Krish does not have 3 cups (which goes with the 1.25 tblsp of sugar)

Answer 18

they never say how many bowls the recipe makes. Does he need 3 cups of pumpkin to make 1 bowl ? or just the 2 cups ?

Answer 19

Or is a bowlful a cup ?

Answer 20

a bowlful is like 1. so 1/2+1/2=1 and 1+1=2, which makes it 1+2=3 all together.

Answer 21

ok, so that means he has to make 3 times what the recipe calls for .

Answer 22

yes so i did 5/6*3=15/6

Answer 23

or it could be 3 * 1.25 = 3.75 = 15/4
(using the original amount that the recipe called for). Unless they are clearer, I don't know what they want.

Answer 24

I guess "with the same proportions of ingredients" might mean using the 5/6.

I would go with your answer.

Answer 25

what about if krish uses the amount of the ingredients (like 5/6 of sugar and sticking with 2 cups of diced pumpkins)? how can i solve for it like that?

Answer 26

you just did. 3*5/6 =15/6 = 5/2 tblsp of sugar

Answer 27

do i subtract? i did this problem by subtracting 15/6-5/6=10/6=1 2/3 <--- answer

Answer 28

If you need to make 3 times the amount as before
and he used 5/6 tblsp of sugar before,
he will need 3*5/6 = 15/6 = 5/2

Are you asking a different question ?

Answer 29

i understood that. but what about the last statement "How many more tablespoons of sugar does he need?"

Answer 30

oh, good point. yes, what you did looks good. He needs 10/6 = 1 ⅔ more than before

Answer 31

how can i write part b (second question) in a wording that says that he used 2 cups of diced pumpkins and 5/6 amount of sugar. basically, how can i make the second question depend on the first question?

Answer 32

You could write

Given 2 cups of pumpkin and 5/6 tablespoon of sugar makes one bowl of Saag Kumro. Then 3 bowls of Saag Kumro requires a total of 2 ½ tablespoons of sugar, or an additional 1 ⅔ tablespoons of sugar beyond the original 5/6 tablespoons.

Answer 33

and that would give me a result of 1 2/3 right?
