. How many pieces of string each

1.5 \mathrm{~cm}

long can be cut from a piece of string

1

metre long?

\newline

Ans:

Convert to Centimeters: Convert the length of the string from meters to centimeters. $\newline$ We know that $1$ meter is equal to $100$ centimeters. $\newline$ So, $1$ meter $= 100$ centimeters.
Calculate Number of Pieces: Divide the total length of the string in centimeters by the length of each piece to find out how many pieces can be cut. $\newline$ The length of the string is $100\,\text{cm}$ , and each piece is $1.5\,\text{cm}$ long. $\newline$ Number of pieces $=$ Total length of string $\div$ Length of each piece $\newline$ Number of pieces $= 100\,\text{cm} \div 1.5\,\text{cm}$
Find Whole Number: Perform the division to find the number of pieces. $\newline$ Number of pieces = $100 \div 1.5$ $\newline$ Number of pieces = $66.666\ldots$ $\newline$ Since we cannot have a fraction of a piece of string, we round down to the nearest whole number. $\newline$ Number of pieces = $66$
