Answer:
Her daughters age: 1/2x
Step-by-step explanation:
Let's say Rani's present age is x. Her age is twice the age of her daughter.
So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.
1/2(20)=daughter's age
so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.
hope this helped :-) <3
Answer: (2.75-2.40)/(2.75) * 100 [Before rounding to the nearest tenth]
Step-by-step explanation:
Formula for percentage decrease = (old-new)/(old) * 100
so substituting in, you get (2.75-2.40)/(2.75) * 100
From here, you can just plug this into a calculator (don't have on me rn)
