I would say moving the decimal point one place to the right is the same as multiplying by 10. Moving the decimal point 2 places to the right is the same as multiplying by 100. If you multiply the numerator and denominator by the same non 0 number an equivilent fraction so moving the decimal points however many places needed to make the numerator and denominator intigers is the same value as the original quotient. Once you have a fraction of integers you can simpify the fraction by dividing the numerator and the denominator by their common factors
The answer is Length = 6cm, width = 9cm. This is because to find 1/4 multiplied by the dimensions, you need to divide by 4. 36 ÷ 4 = 9, and 24 ÷ 4 = 6. I hope this helps!
