Round to the 10th Pl. to make an estimate and solve 54.2+35.6

Answer 1

To round to the nearest tenth:

• 54.2 rounds to 54.2 (already at the tenth place)
• 35.6 rounds to 35.6 (already at the tenth place)

Now, we can estimate the sum:

54.2 + 35.6 = 89.8

So, the estimated sum of 54.2 and 35.6 is approximately 89.8.
