Question

for what value of k in each of the following pairs represents a pair of equivalent rational number wrong answers will be reported​

Answer 1

Answer:

The given sentence needs to be filled with the most suitable determiner. We have to determine the amount of 'sugar'. It is an uncountable noun. Option A is incorrect, as we use 'any' with negative sentences and questions, like - She didn't have any sugar./ Did she have any sugar? Option B is incorrect because 'Much' is usually used with uncountable and abstract nouns like 'time'. Here, 'much' can be used to ask questions - How much sugar do you want? Option D is incorrect, as 'many' is used for countable nouns. Option C is correct, as 'some' is used for uncountable nouns and in positive sentences.

$a) \: \: \frac{3}{5} \: and \: \frac{12}{k}$

$= > \frac{3}{5} \times \frac{4}{4} = \frac{12}{20}$

$b) \: \frac{ - 2}{9} \: and \: \frac{k}{45}$

$= > \frac{ - 2}{9} \times \frac{5}{5} = \frac{ - 10}{45}$

Hope this may help you!
