Answer 1

$\sf\large\underline{Given:}$

$\tt{\implies Required\:for\:a\: shirt=1.8m}$

$\tt{\implies Total\: length\:of\: clothes=45}$

$\sf\large\underline{To\: Find:}$

$\rm{\implies How\: many\: shirt\: can\:be\:made\: from\:45m\: clothes}$

$\sf\large\underline{Solution:}$

• Simply by dividing we get number of shirt that how many shirt can be made from the total length of clothes. If the length of clothes for a shirt 1.8m than calculate calculate number of shirt from 45. Here we can divide 45m by 1.8]

$\rm{\implies No\:of\: shirts=\frac{Total\: length}{length\:of\: clothes\:for\:a\: shirt}}$

$\rm{\implies No\:of\: shirts=\dfrac{45}{1.8}}$

$\rm{\implies No\:of\: shirts=25}$

$\sf\large{Hence,}$

$\rm{\implies No\:of\: total\:peice\:of\:shirts=25}$

• The fractions in which the denominators are 10, 100, 1000 etc. are known as decimal fractions.
• Numbers written in decimal form are called decimal numbers or simplify decimals.
• A decimal has two parts -- whole number part and decimal part.
• The number of digits contained in the decimal part of a decimal gives the number of its decimal places.
• Decimals having the same number of decimal places are like decimals, otherwise they are unlike decimals.
• We may convert unlike decimals into like decimals by annexing the desired number of zeros at the end of the decimal part.
