Answer:240
Step-by-step explanation:You get 240 because 60X4 is 240. to get the 4, you need to use 100-20, then therer would be 80. 80 divided by 20 is 4, which is the amount of water.
Ms. Maryna needed 240g water to add to 60g of sugar to make a syrup that is 20% concentrated
Given that,
Ms. Maryna need to add to 60g of sugar to make a syrup that is 20% concentrated.
We have to determine,
How much water does she need.
According to the question,
Ms. Maryna need to add to 60g of sugar to make a syrup that is 20% concentrated.
If Maryna need 20% sugar by mass,
Then,
[tex]= \dfrac{20}{100} = \dfrac{1}{5}[/tex]
It is 1/5 of the total mass is sugar,
And ,
Total water needed is,
[tex]= 1-\dfrac{1}{5} \\\\=\dfrac{5-1}{5}\\\\= \dfrac{4}{5}[/tex]
It needed 4\5 times of water.
Then,
Maryna needed times as much water as sugar,
[tex]= \dfrac{4}{5} \times \dfrac{5}{1}\\\\= 4 \ times[/tex]
Maryna needed 4 times as much water as sugar.
Maryna need water to add in syrup = 4 × 60g = 240g.
Hence, Maryna needed 240g of water to add to make a syrup.
