Blue tiles

Studdy Solution

STEP 1

What is this asking? How many blue tiles does Helmut need if his mosaic uses 290 tiles total, and he's already using 68, 64, and 72 green tiles? Watch out! Don't forget, there are *three* different shades of green tiles!
We need all of them to figure out the total number of green tiles.

STEP 2

1. Sum the green tiles
2. Subtract green from total

STEP 3

Alright, let's **add up** all those green tiles!
We've got 68, 64, and 72 green tiles.
We're doing this to find the *total* number of green tiles Helmut is using.

STEP 4

68+64+72=20468 + 64 + 72 = 204

STEP 5

So, Helmut is using a **total** of 204204 green tiles.
Cool!

STEP 6

Okay, we know Helmut has 290290 tiles *total* and 204204 of them are *green*.
To find the number of *blue* tiles, we need to **subtract** the number of green tiles from the total number of tiles.
This is because the total number of tiles is made up of blue tiles *plus* green tiles.

STEP 7

290204=86290 - 204 = 86

STEP 8

That means Helmut needs 8686 **blue tiles**!

STEP 9

Helmut needs 8686 blue tiles to finish his mosaic.
