How many different ways can you write a fraction that has a numerator of 2 as a sum of fractions

1 answer:

7 0

At least you can write it as the sum of half of it twice, that is:
2/x = 1/x + 1/x
whatever x number you have, for example:
2/5 = 1/5 + 1/5

But then, you can express a fraction in many different ways, for example again:
2/5 = 1/5 + 1/5 = 2/10 + 2/10
= 1/10 + 1/10 + 1/10 + 1/10
so there are an infinite ways of expressing such a fraction.

Enter your answer in the box.

TEA [102]

This is an arithmetic series,
so
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73

S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925

Answer : 925

a barn casts a shadow that is 12 meters long while a tree in the yard casts a shadow that is 8 meters long. how long is the tree

STALIN [3.7K]

Using proportion...

length of barn length of tree
-------------------------------- = --------------------------------
length of barn's shadow length of tree's shadow

20 x
---- = ---
12 8

Using cross-multiplication...

20 x 8 = 12x
160 = 12x
x = 13 1/3 or 13.3333

The tree is 13 1/3 meters long.

Answer:

Step-by-step explanation:

$y =\frac{x+2}{x-4}\\\\y*(x-4)=x+2\\\\yx-4y = x+ 2\\\\yx-4y-x = 2\\\\yx -x = 2 +4y\\\\x(y-1)=2+4y\\\\x=\frac{2+4y}{y-1}$
