I = prt
450 = 3000 x r x 3
450 = 9000r
450/9000 = 9000r/9000
r = 0.05

What is 4 3/4 as a improper fraction
Alexus [3.1K]

Answer: 19/4

Explanation: To write a mixed number as an improper fraction, first multiply the denominator times the whole number and then add the numerator.

So here, we multiply the denominator which is 2 times the whole number, 3, and then we add the numerator. So we have (4 x 4) + 3 which simplifies to 19.

Finally, we put our new number over our old denominator and we have our answer which is 19/4.

So 4 and 3/4 can be rewritten as the improper fraction 19/4.
