1st Step:We should first change them all to have a common denominator.
2nd Step:We should find the least common multiple
4×1=4 8×1=8 16×1=16
4×2=8 8×2=16
4×3=12
4×4=16
LCM is 16
\(\frac{1*4}{4*4}\) + \(\frac{1*2}{8*2}\) +\(\frac{1}{16}\)
\(\frac{4}{16}\) + \(\frac{2}{16}\) + \(\frac{1}{16}\)
\(\frac{7}{16}\)
\(\frac{7}{16}\) is the fraction of the page that is used in total.
