Mike J answered Multi-step problem, but very easy.Take the 4 before the decimal point. This is your whole number.The .8 is "8 tenths", which is 8/10 written as a fraction.Now you have 4 and 8/10. The 8/10 can be simplified to 4/5 (divide the numerator and denominator by 2 to simplify).This now leaves you with 4 and 4/5. You can leave it as a mixed number or you can change it to an improper fraction.You have 4 wholes. One whole is 5/5. Multiply this by 4 and you will get 4 equaling to 20/5. Now, add the 4/5 to this.20/5 + 4/5 = 24/5.Those are your two possible answers.
