Two equal fractions would be 4/6 and 6/9.
Both are related because u can multiply the answer to find a devision problem and you can divide a answer to find ur multiplication problem and find ur answer hope this helps
( 2a2 - 2b - 1 ) Is the answer when simplifying the expression.
I’m pretty sure c is supposed to be 37.4 instead of 27.4
Try this solution:
let the unknown two-digits number be 'xy'.
Then it is possible to write any two-digit number as 10x+y, where x - the tens digit and y - the unit digit.
Using the rule described above the phrase 'the tens digit of a number is twice the units digit' may be written as x=2y.
Using the same rule the phrase 'if the digits are reversed, the new number is 36 is less than the original number' may be written as (10x+y)-(10y+x)=36.
These two equations may be resolved as system of two equations:

Check: the original number is 84, the new number is 48; difference is 84-48=36.
answer: 84
