A piece of rope is 7m 20cm long. It is cut into 2 pieces. One piece is shorter than the other by 1m 80cm. Find the length of the shorter piece.

$\huge\purple{\underline{\underline{Answer:}}}$

$\bf\underline{Given:}$

• A wood piece 100 cm long
• Cut into 2 pieces

$\bf\underline{Solution:}$

Let shorter piece be x.

Longer piece = $2x + 10cm$

x + 2x + 10 m = 100 cm

=> $3x + 10 m$ = 100

=> $3x$ = 100-10

=> $3x$ = 90

=> $x = \frac{90}{3}$

=> $x = 30 cm$

$x = 30 cm$ Ans.

$2x + 10 cm= 2×30 + 10$

=> $60 + 10 m$

=> $70 cm$ Ans.
