To convert a fraction into decimal, just take the number on top which we called the numerator and divide it by the number at the bottom which we called the denominator.

2/3

How it comes :

$2÷3=0$ bring down the decimal point.

$20÷3=6$ and carry the remainder $2$ to make $20$

$20÷3=6$ and carry the remainder $2$ to make $20$

$20÷3=6$ and carry the remainder $2$ to make $20$

etc...

This gives the recurring decimal 0.6666...

If we round off to two decimals , then it becomes 0.67.

Hence, decimal fraction of 2/3 = 0.67.

We want the temperature when F=C.

We know that, F = C x 95 + 32

So substituting C For F, we have C = -40o

Therefore,  C = -40. 

Thus when C = -40, we have C = F

If we read the question clearly twice, we can understand that the name of the horse on which the cowboy rides into town is FRIDAY.

In an algebraic expression, like terms are terms that contain the same variables raised to the same powers. Calculating x-squared plus x-squared is a matter of combining like terms. 

Now x^2 + x^2 = 2x^2

Hence, x-squared plus x-squared is equal to 2 times x squared.

The Word LOGARITHMS  contains 10 letters.

To find how many 4 letter words we can form from that = P410 =10x9x8x7 = 5040.

Let the man's rate upstream be x kmph and that downstream be y kmph.

Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.

		x x 8	4		= (y x 4)

	44	x =4y
	5

y =	11	x.

Required ratio =		y + x		:		y - x
		2				2

=		16x	x	1		:		6x	x	1
		5		2				5		2

   = 8 : 3.

The area in which two types of air masses meet is called Front. There are two types of fronts. They are 

1) Cold front

2) Warm front

When a cold air mass pushes a warm air mass, it is called as Cold front. Similarly, when a warm air mass pushes the cold air mass, it is called as warm front.
