Question

There are 5 Christmas trees in the town square. Four of the trees have 155 ornaments on them. The 5th tree is the largest and has 1/5 more ornaments than the previous 4 trees. How many ornaments are on all 5 trees?​

Answer 1

806 ornaments

Explanation:

Let's first calculate the number of ornaments on the fifth tree.

Since the fifth tree has 1/5 more ornaments than the others, we need to find out what 1/5 of 155 is:

1/5 x 155 = 155/5 = 31

Therefore, the fifth tree has 31 more ornaments than the others, meaning it has 186 ornaments in total.

Add them all together:

155 + 155 + 155 + 155 + 186 = 806

Answer 2

806 ornaments

Explanation:

We first find how many total ornaments are on the first four trees:

4 trees × 155 ornaments/tree = 620 ornaments

We then multiply this number by 1 + 1/5 to find the number of ornaments on the fifth tree:

155 ornaments × (1 + 1/5)

= 155× 1.2 ornaments

= 186 ornaments

We finally add up the number of ornaments on all five trees to find the total number of ornaments:

620 ornaments + 186 ornaments = 806 ornaments

Therefore, there are a total of 806 ornaments on all five trees.
