Question

If the length and width of a sheet are $\frac{1}{4}m$ and $\frac{1}{5}m$, respectively, then complete the following equations.
Multiplication equation:
$\frac{1}{4}m\times \frac{1}{5}m=\frac{\left[\right]}{\left[\right]}\text{sq m}$
Division equation:
$\frac{1}{4}m=\frac{\left[\right]}{\left[\right]}\text{sq m}÷\frac{1}{5}m$

Answer 1

The length of a sheet is $\frac{1}{4}m$, and the width of the sheet is $\frac{1}{5}m$.
Area of sheet $=$ Length $\times$ Width
$=\frac{1}{4}m\times \frac{1}{5}m=\frac{1}{20}\text{sq m}$
The multiplication equation:
Quotient $\times$ Divisor $=$ Dividend
Here, quotient $=\frac{1}{4},$ divisor $=\frac{1}{5},$ and dividend $=\frac{1}{20}$
Corresponding or related division equation:
Quotient $=$ Dividend $÷$ Divisor
$=\frac{1}{4}m=\frac{1}{20}\text{sq m}÷\frac{1}{5}m$
Hence, the correct option is D.
