Q. multiplications?)

\newline

9

. To stitch a shirt,

2 \mathrm{~m} 15 \mathrm{~cm}

cloth is needed. Out of

40 \mathrm{~m}

cloth, how many shirts can be stitched and how much cloth will remain?

\newline

(Hint: convert data in

\mathrm{cm}

.)

Convert to centimeters: First, convert everything to centimeters because we need a common unit to divide easily. $\newline$ $1\,\text{m} = 100\,\text{cm}$ , so $2\,\text{m}\,15\,\text{cm}$ is the same as $215\,\text{cm}$ (because $2\times100\,\text{cm} + 15\,\text{cm}$ ).
Convert total cloth length: Now, convert the total cloth length into centimeters. $40\,\text{m}$ is $4000\,\text{cm}$ (because $40\times100\,\text{cm}$ ).
Divide total cloth: Next, divide the total cloth by the cloth needed for one shirt. $4000\,\text{cm}$ divided by $215\,\text{cm}$ equals approximately $18.6$ .
Calculate number of shirts: Since we can't make a fraction of a shirt, we can make only $18$ shirts.
Calculate remaining cloth: Finally, calculate the remaining cloth. $4000\,\text{cm} - (18 \,\text{shirts} \times 215\,\text{cm} \,\text{per} \,\text{shirt})$ equals $4000\,\text{cm} - 3870\,\text{cm}$ , which is $130\,\text{cm}.$
