Okay, here we have this:
We need find the least common denominator between 7/10 and 17/25:
For the denominators (10, 25) the least common multiple (LCM) is 50.
Therefore, the least common denominator (LCD) is 50.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
7/10=7/10×5/5=35/50
17/25=17/25×2/2=34/50
