Priya has a piece of string 5/6 yard long. She cuts 3/5 of the piece of string for a craft. What is the length of the string lef

Solnce55 [7]

Total length of the string = $\frac{5}{6}$ yard

Length of string used for craft = $\frac{3}{5}$ of total length of string

= $\frac{3}{5}$ of $\frac{5}{6}$

= $\frac{3}{5} \times \frac{5}{6}$

= $\frac{3}{6}$ yard

Length of the string left after use = Total length of the string - Length of string used for craft

Length of the string left after use = $\frac{5}{6}-\frac{3}{6}$

= $\frac{2}{6}$

Reducing it to the lowest term, we get

= $\frac{1}{3}$ yard

Therefore, the length of string left is $\frac{1}{3}$ yard.
