So when you have something like 'split up £54 in ratio 4:5', it really just means split £54 into 4 parts and 5 parts. But we can't do that without working out 1 part.
So the way to find 1 part is to add up all the parts (4 + 5) and divide 54 by that number.
So 4 + 5 is 9, and 54 divided by 9 is 6.
So if 1 part is 6, that means 4 parts is 4 times 6, which is 24.
Equally, if 1 part is 6, 5 parts is 5 times 6, which is 30.
Therefore, £54 split up in a ratio of 4:5 is 24:30.

Step-by-step explanation:
Answer:
x² - 6x + 9
Step-by-step explanation:
(x - 3)²
= (x - 3)(x - 3)
Each term in the second factor is multiplied by each term in the first factor
= x(x - 3) - 3(x - 3) ← distribute both parenthesis
= x² - 3x - 3x + 9 ← collect like terms
= x² - 6x + 9 ← in standard form
Answer:
multiplication
Step-by-step explanation:
The evaluation of ...
13 -2·3 +4/4 +4
starts with the multiplication, because there are no exponents or parentheses.
13 -6 +4/4 +4
Next is the division:
13 -6 +1 +4
Finally, the addition and subtraction:
7 +1 +4
8 +4

We have assumed your x is not a variable, but is intended to indicate multiplication. We have also assumed that your "divided by" implies no particular grouping, so that the numerator is the first preceding number and only the first following number is in the denominator.
2 3/5=2*5+3/5=13/5=2,6;
2,6²=6,76;
2 3/5=√6,76
