3/10 - 1/5 lets make a common denomiator of 10. to do that, we will multiple the bottom and the top of 1/5 by 2 1 * 2= 2 5*2 = 10 so now we have 2/10, so 3/10 - 2/10 when you subtract fractions with common denominators, you never subract the denominators,meaning you don't subract the bottoms, only the tops. so, 3 - 3 = 1 so your answer is 1/10. Brainliest please!
