Solve for y: 2½y = ⅝ Answer in simplest form.

MrMuchimi

Step-by-step explanation:

$2 \frac{1}{2} y = \frac{5}{8}$

Convert Mixed number to improper fraction.

$2 \frac{1}{2} = \frac{5}{2}$

Equate

$\frac{5}{2} y = \frac{5}{8}$

Cross Multiply

$5y \times 8 = 2 \times 5 \\ 40y = 10$

Divide both sides of the equation by 40

$\frac{40y}{40} = \frac{10}{40}$

Simplify

$y = \frac{1}{4}$
