Answer» Question :- $\huge\frac{17}{10} - \frac{20}{25}$ ANSWER :- First we have to do the LCM of the denominators as they are not equal . LCM of 10 and 25 is => 50 Now we have to also equal the numerator by multiplying the number which should be multiplied to its denominator to get 50. So, $\frac{17}{10} = \frac{17×5}{10×5} = \frac{85}{50}$ $\frac{20}{25} = \frac{20×2}{25×2} = \frac{40}{50}$ HENCE , equal . Now we will substract . $\frac{85-40}{50} \: = \: \frac{45}{40}$ Simplified , $\frac{9}{8} \: or \: 1\frac{1}{8}$ Final Answer :- $\frac{9}{8} \: or \: 1\frac{1}{8}$ Hope it HELPS friend !
