Isa has collected 135 stickers. This is 5/8 of the total number of stickers needed to complete the album. How many stickers are needed to complete the album?

Let $T$ be the total number of stickers needed to complete the album. Isa has collected 135 stickers, which represent $\frac{5}{8}$ of the total.

$$135 = \frac{5}{8} \times T$$

To find the total number of stickers, multiply both sides of the equation by the reciprocal of $\frac{5}{8}$, which is $\frac{8}{5}$.

$$T = 135 \times \frac{8}{5}$$

$$T = \frac{135 \times 8}{5}$$ $$T = \frac{1080}{5}$$ $$T = 216$$

The total number of stickers for the album is 216.

The total number of stickers for the album is $\text{216}$.
