Q. Choose all the common denominators for 41 and 107.A. 10B. 20C. 24D. 32E. 40
Find Common Denominators: To find common denominators for the fractions(1)/(4) and (7)/(10), we need to find multiples of the denominators 4 and 10 that are the same.
Multiples of 4: The first few multiples of 4 are 4,8,12,16,20,24,28,32,36,40,…
Multiples of 10: The first few multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, ...
Identify Common Multiples: Now we look for the common multiples from the lists above. The common multiples of 4 and 10 within the given options are 20 and 40.
Check Option A: We check the options given in the problem to see which ones are common multiples of 4 and 10. Option A (10) is not a multiple of 4, so it is not a common denominator.
Check Option B: Option B (20) is a multiple of both 4 and 10, so it is a common denominator.
Check Option C: Option C (24) is a multiple of 4 but not a multiple of 10, so it is not a common denominator.
Check Option D: Option D (32) is a multiple of 4 but not a multiple of 10, so it is not a common denominator.
Check Option E: Option E (40) is a multiple of both 4 and 10, so it is a common denominator.
