What is 4 1/5 : 3/4

5.6 or 28/5 unless you want a mixed number then it would be 5 3/5

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Next, add the whole number to the left of the decimal.

Reduce the fractional part of the mixed number.

Convert the mixed number into an improper fraction first by multiplying the denominator by the whole number part and add the numerator to get the new numerator. Place the new numerator over the old denominator

(keep change flip), 4 1/5 = 21/5

21/5 x 4/3 = 28/5 or 5 3/5
