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

Answer:

24 blocks long

Answer 2

Answer:

24 blocks.

Step-by-step explanation:

$\frac{1}{6} +\frac{5}{8} =5$ blocks

$\frac{8}{48} + \frac{30}{48}=\frac{38}{48}\\\\ \frac{48}{48} -\frac{38}{48} =\frac{10}{48}$

$\frac{10}{48}$ 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.
