Question

Little Tommy built a train out of LEGOS. One-sixth of the train was made with blue blocks, 5/8 of the train was made with red blocks and the remaining five blocks were yellow.

How many LEGO blocks long was Tommy's train?

Answer 1

24 blocks.

Explanation:

`(1)/(6) +(5)/(8) =5` blocks

`(8)/(48) + (30)/(48)=(38)/(48)\\\\ (48)/(48) -(38)/(48) =(10)/(48)`

`(10)/(48)` is 5 blocks

You can use ratios to find out how many blocks for each color now. (I'm too lazy)

Blue blocks: 4 blocks

Red blocks: 15 blocks

Yellow blocks: 5 blocks

4+15+5=24 blocks in total.

Answer 2

24 blocks long
