Maria’s grandmother is making her a dress. She has 23.8 yards of fabric

more or less 5.6 sections
Explanations:
[tex]\frac{23.8}{4.2}\approx5.6666667[/tex]Since in 1 section, she wants 4.2 yards and she has 23.8 yards in total it means she'll need 23.8 yards / 4.2 yards
Since the number is not exact in the answer I gave you I truncated it.
