Hi im in 5th grade an I really need help on my math homework. The question is "Which decimal rounded to the nearest tenth is 0.9"? Please help me I would be very happy if you could. :) -Brooklyn

0.85, 0.86, 0.87, 0.88 or 0.89

Step-by-step explanation:

This is because, to round up a number to the nearest, the number after that number must be greater than or equal to 5. So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth since the digit after the 8 is greater than or equal to 5. So, 0.85 rounds to 0.9 to the nearest tenth, 0.86 rounds to 0.9 to the nearest tenth, 0.87 rounds to 0.9 to the nearest tenth, 0.88 rounds to 0.9 to the nearest tenth and 0.89 rounds to 0.9 to the nearest tenth.

So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth is 0.9
