Answer 1

4.5 m answer ok broooooooooooooooooo

Answer 2

The length of the original piece of String is 4.5m

Explanation:

Given:

1.  A piece of string was cut into 12 equal pieces

2. The length of 5 such pieces is 15/8 m

To find:

The length of the original piece of string

From the given value,

==> The length of 5 such pieces is 15/8 m

==> 5 pieces = 15/8

==> Find tha value of 1 piece

==> Divide by 5 on both sides

==> 5/5 = (15/8)/5

==> 1 piece = 3/8 m

A piece of string was cut into 12 equal pieces

==> 1 piece = 3/8 Length

==> To find 12 piece,

==> Multiply by 12 on both sides

==> 12 piece = 3/8×12

==> 12 piece = 3(12)/8

==> 12 piece = 3(3)/2

==> 12 piece = 9/2 m

==> 12 piece = 4.5m

B) 4.5 cm

The length of the original piece of String is 4.5m
