which decimal is equal to 1/5a. 0.2b. 0.15c. 0.1d. 1.50

If you do 1 literally divided by 5, because that's basically what it's asking for, you get .2, so it's A

1/5 can also be replaced as 20/100 you just multiply the denominator and numerator by 20. I think it is easier this way because decimals are out of 100 so if you can find an equal fraction that is out of 100 for the denominator the numerator can be turned into decimal form
