Explain why you cannot multiply or divide by zero to find equal ratios
zero isnt a positive or a negative number, so you cannot multiply or divide a number that is not there because it is considered an undefined number
Equivalent fraction or equivalent ratios are one which may look different but are same numbers i.e. by multiplying or dividing a fraction by a same non -zero number we obtain a fraction equivalent to the given fraction.
Hence, we cannot multiply or divide by zero to find equal ratios.
