y = 9/5

Mrshape:
solve the simultaneous equations
2x-8=7y
-14y+4x=16

x= 1
y = -6/7

Mrshape:




question 35

the area under 2 radi and an arc is?

sector

Mrshape:
Let x be the unknown fraction

X=4.35....equ1


Multiply through by 100


100x=435.35........equ2

Subtract equ 1 from 2

99x=431
X=431/99



The is how you turn all decimal to fractions weather reoccurring or terminating

also, this doesn't work for terminating decimals.. It only works for recurring decimals

My last score has not been updated.

The is how you turn all decimal to fractions weather reoccurring or terminating

but it is not in all cases that we multiply by 100. It can be 10 or 100 or 1000 depending on the numbers of digits after decimal

Kareayo:
this is a recurring decimal, I.e 4.353535...

For recurring decimal, the denominator is always 9 or 99 or 999 etc depending on the number of digits recurring..

In this case, our denominator is 99 since it is only two digits that are recurring (3 & 5)

To get numerator, this will be (the main number without the decimal) minus (the actual number before the decimal). I.e 435 - 4 = 431

Therefore 4.35... = 431/99

here is it

difference between 2 numbers is subtraction of one number from the other. It can also be the other way round.
That is, difference between 6 and 9 is either 6 minus 9 or 9 minus 6
