Answer:
larger number x = 37 and smaller number y = 12
Step-by-step explanation:
Let the larger number be <em>x </em>and the smaller number be <em>y</em>.
Sum of the numbers is 
....(1)
∴<em> 
</em>
Now, 3 times of the smaller number = 3<em>y</em>
According to question,
Now, by substituting the value of y in (2)
Now,<em>y</em> = 49 - <em>x</em> and
So the larger number x =37 and smaller number y = 12.
First basically solve.
Next, take the number after the decimal point and see if it's larger than 5 or lesser than 4.
Than, Look at the number before the decimal point and relate back to step 2 (Next) if the number is higher than one. Add by 1 to the number before the decimal.
Example:
4.45
vvvv
4.(4)5 > The 4 is lesser than 4, so the number before the decimal point is keep the same.
