40 g sultanas

Answer 1

Answer:

1.44kg of sugar

Step-by-step explanation:

First, you need to set up the problem:

225 milliliters of syrup per 180 grams of sugar

Now you figure out how many grams of sugar per ONE milliliter

225mL/180g = 0.8g/mL = 0.8 grams of sugar per one milliliter

Turn 1.8L into milliliters by multiplying it by 1000 (1.8 x 1000 = 1800)

We now know Angela has 1800mL of syrup

We now go back into the orignal equation: 0.8g/1mL

If you multiply both amounts of sugar and syrup by 1800 you get 1800mL of syrup (what Angela has) and 1440g of sugar (what Angela needs)

So there are 1440g of sugar per 1800mL of syrup

Angela needs 1440g of sugar

All we need to do now is convert g into kg, and we do that by dividing by one thousand: 1440/1000 = 1.44kg

Angela needs 1.44kg of sugar
