Answer:
terminates after 3 places of decimal
Step-by-step explanation:
Let x=7/20×25 be a rational number.then x has decimal expansion
x = 7/(20 * 25)
20 * 25 = 20 * 5 * 5
= 100 * 5
x = 7/ (100 * 5)
multiply numerator & denominator by 2
x = 14 / ( 100 * 5 * 2 )
x = 14/1000
x = 0.014
decimal expansion terminates after 3 places of decimal
