Step-by-step explanation:if I am right you just have to do the equacion
Answer:
720 grams of flour.
10.8 grams of salt.
14.4 grams of yeast
36 ml of oil.
Step-by-step explanation:
The recipe is:
600g flour
9g salt
12g yeast
30ml oil
500ml water
Now we use 600ml of water.
We can take the quotient between the amount of water we use and the amount of water in the recipe, this is:
600ml/500ml = 1.2
Then the ratio between the quantities we need to use and the quantities un the recipe should be always 1.2
Or the quantities that Eli needs to use will be 1.2 times the ones shown in the recipe.
Then she needs to use:
1.2*600g flour = 720 grams of flour.
1.2*9g salt = 10.8 grams of salt.
1.2*12g yeast = 14.4 grams of yeast
1.2*30ml oil = 36 ml of oil.
This is a simple division problem. Since there are 236 crayons, in groups of ten, there will be 6 left over because there is a 6 in the ones place.
