Given :
Heidi uses 5 grams of tea leaves to make 25 fluid ounces of tea.
Last week she made 75 fluid ounces of tea.
To Find :
How many grams of tea leaves did Heidi use to make tea last week.
Solution :
Let, x gram of leaves are required last week.
So,
![(x)/(5)=(75)/(25)\\\\x = 5*(75)/(25)\\\\x = 5* 3\\\\x = 15 \ grams](https://img.qammunity.org/2021/formulas/mathematics/high-school/stfixwj45q8p3j7u789rbvgo4knkofepy4.png)
