Answer:
45%
Explanation:
Since we are given the total spent (denominator) and the amount spent on the fruit (numerator) we can simply divide one by the other which would give us the percentage, in decimal form, of the total that he spent on fruit. We then multiply this decimal by 100 to get the actual percentage value like so...

0.45 * 100 = 45%
Finally, we can see that the percentage of the total amount that was spent on fruit was 45%.
