Answer:
11.43%
Step-by-step explanation:
Since both the unit of measurement given in the question are different. We need to change them to be the same. It does not matter if we change both to m or cm. But here I choose to change to cm.
3.5m = 3.5 x 100 cm = 350 cm
Then we put the number we want to convert as the numerator and the total as the denominator to give us the fraction.
40/350
To covert the fraction into percentage, we multiply it by 100%.
40/350 x 100 = 4000/350 = 11.43% (nearest hundredth)
