Answer:
1/15
Step-by-step explanation:
Dividing a fraction can sometimes be seen as multiplying it by another fraction.
So instead of doing (1/5)/3 we can write it like this:
1/5 * 1/3
And since multiplying something by one third is equivalent to dividing it by three, nothing has really changed.
So now we can multiply the fractions.
First we'll take the numerator (the number above the line) of 1/5 and multiply it by the numerator or 1/3.
1 * 1 = 1
Then we do the same for the two denominators (the numbers <em>below</em> the line)
5 * 3 = 15
So now we've turned 1/3 * 1/5 into: (1*1)/(3*5),
Then simplified it to:
1/15

Describe what you notice when you create the inverse ratio.
- How do you describe it?
- What do you notice?
- How do you create it?
➜︎Answer
A function composed with its inverse function yields the original starting value. Think of them as "undoing" one another and leaving you right where you started. Basically speaking, the process of finding an inverse is simply the swapping of the x and y coordinates.
- You can describe a inverse ratio by saying how it works
- You can notice the difference
- You could possibly know
Answer:The present age of both of them are Christopher = 42 years, and Ishaan = 84 years.
Step-by-step explanation: Solution:
Let present age of:
Christopher =
x
yrs
Ishaan =
2
x
yrs ( given that Ishaan is 2 times as old as Christopher)
35 yrs ago:
Age of Christopher = (
x
- 35)yrs
Age of Ishaan = (
2
x
- 35) yrs
According to question, 35 yrs back, Ishaan was 7 times older than Christopher.
Therefore
7 X (
x
- 35) = (
2
x
- 35)
7
x
- 245 =
2
x
- 35
7
x
-
2
x
= 245 - 35
5
x
= 210
x
= 42
So present age of Christopher =
x
= 42 yrs
&
Present age of Ishaan =
2
x
= 84 yrs
Check your solution:
As 84 is 2 times of 42 so Ishaan is 2 times older than Christopher.
35 yrs ago, Christopher was (42 - 35) = 7 yrs old and Ishaan was (84 - 35) = 49 yrs old so Ishaan was 7 times older than Christopher then.
