Question

Number system!!!!
xy is a number that is divided by ab where xy 3 years ago

Answer 1

since.,
\[\frac{ xy }{ ab } = 0\]

And
\[xy < ab\]

So they answer is very simple
\[\frac{ xy }{ ab } = 0 => \frac{ xy }{ 1} = 0 \times ab = 0\]

so ab can be any no where xy is 0 and 0 divided by any no is either zero or considered infinity

Therfore ab can also be taken as 1

Answer 2

but answer is 99

Answer 3

any number that divides 0 always yields zero no matter what that number is..

Answer 4

See :

\[\frac{ xy }{ ab } = 0.xyxyxyxyxyx.......\]

where,

\[xy < ab\]

we know that quantity :
0.xyxyxyxyxyxy........

is Irrational

Therefore it can also be written as:

\[\frac{ xy }{ 100 } +\frac{ xy }{ 1000 } + \frac{ xy }{ 10000 } + \frac{ xy }{100000}+...\]

Now takin' \[\frac{ xy }{ 100 }\] as common

Therefore:

\[\frac{ xy }{ 100 }\left( 1 + \frac{ 1 }{ 10 } + \frac{ 1 }{ 100 } + \frac{ 1 }{ 1000 } + .. \right)\]

\[=\frac{ xy }{ 100} \times \frac{ 1 }{ (1 - 100)}\]

Remember convergence/divergence of power series !

\[= \frac{ xy }{ 99 }\]

Therefore ,we conclude that:

\[\frac{ xy }{ ab } = 0.xyxyxyxyxy... = \frac{ xy }{ 99}\]

Therefore ab is:

\[ab = 99\]

Answer 9

A pineapple was found to have two sets of opposing spirals formed by its leaves. The clockwise spiral has x leaves. The number of leaves in the counterclockwise direction is 13 more than that in the clockwise direction. These leaf numbers are consecutive numbers in the Fibonacci sequence.

Which equation is true for the number of leaves in the two spirals?
Answer

The quantity x plus 13 divided by x equals 1.6

X divided by 13 equals 1.6

The quantity x plus 13 divided by 13 equals 1.6

13 divided by x equals 1.6
