Answer:
120%
Step by step explanation
Step 1: We make the assumption that 4.50 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=4.50$100%=4.50.
Step 4: In the same vein, $x\%=5.40$x%=5.40.
Step 5: This gives us a pair of simple equations:
$100\%=4.50(1)$100%=4.50(1).
$x\%=5.40(2)$x%=5.40(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{4.50}{5.40}$
100%
x%=
4.50
5.40
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{5.40}{4.50}$
x%
100%=
5.40
4.50
$\Rightarrow x=120\%$⇒x=120%
Therefore, $5.40$5.40 is $120\%$120% of $4.50$4.50.
Hope this kinda helped
