Hi::
Read ratio topic in mif https://www.mathsisfun.com/numbers/ratio.html
Don't understand how to write in fraction There are 3 blue squares to 1 yellow square
It is given 3:1 but in fraction it say numerator And denominator numerator is part we have and denominor is the whole is divided into
Explain this??
Okk!,, it takes long time
Bob wrote Yes. See post 7.
B
Means? ?
Hmm!!!
If we know x then the value of y is determined!!!! In question 1
Uff!!!
So question 1 ans is D? ?
Can you Clearify Question 2,3,4???
I assumed this meant x is 50% of y,
That is not given in my question
we dont know value of x
so why ans is 2x
Arithmetic mean formula is A=(x+y)\2
Is it true??
He is saying that y =5000\x????
X percent is x\100
Check question 1 I don't understand your formula
Q1. D is not a possible answer as one of the other three must be true.
I tried this:Now subtract:
Why u subtract???
Hehe I know all these formulas
eg . An increase of 10% is the same as multiplying the original by 1.1
and a decrease of 20% is the same as multiplying by 0.8
Means???
Y is 2 time x
