Answer
Estimate: 20 $\div$ 4 = 5
Exact: 4.175
Work Step by Step
20.04 $\div$ 4.8
Lets First find Estimate:
20.04 (rounded to) 20
4.8 (rounded to) 4
20.04 $\div$ 4.8 = 20 $\div$ 4 = 5
Now, lets find Exact:
20.04 $\div$ 4.8
= $\frac{20.04}{4.8}$
= $\frac{2004}{480}$ (multiply numerator & denominator by 100)
= $\frac{2004}{480}$
= $\frac{2004\div12}{480\div12}$ (divide by common factor 12)
= $\frac{167}{40}$
= 4.175 (By solving we get)
