Question

Kaya's score in the gymnastics competition is 15.4 when rounded to the

nearest tenth. Which of the following is her actual score?

Answer 1

C) 15.395

Explanation:

If we round all of the numbers to the tenth place, we'll get

A) 15.333 - 15.3 (3 is less than 5 so the 3 in the tenths place does not get rounded up)

B) 15.496 - 15.5 (9 is more than 5 so the 4 in the tenths place gets rounded up to a 5)

C) 15.395 - 15.4 (9 is more than 5 so the 3 in the tenths place gets rounded up to a 4)

At this point, we can tell that C should be the right answer, but we can check D anyway:

D) 15.349 - 15.3 (4 is less than 5 so the 3 in the tenths place does not get rounded up)

Answer 2

It should just be 15.4 because there are no digits after .4
