Josh says that 3/8 is the same as 38% explain why he is wrong.

Answer 1

While 3/8 is .375.
This multiplied by 100% is 37.5%. So you could round up and get 38%, but if your explaining why it is wrong then 38% isn't specific enough for what the problem is asking. The actual percent is 37.5%.
Hope this helps.

Answer 2

Divide the numerator by the denominator and multiply the quotient by 100. Then you'll have a percentage to compare with 38%.
