Answer:

The answer should be a letter which is t.

Step-by-step explanation:

1) Simplify 2/3t to 2t/3.

$\frac{2t}{3} \times 1 \frac{1}{2}$

2) Convert 1 1/2 to improper fraction. Use this rule: a b/c = ac+b/c.

$\frac{2t}{3} \times \frac{1 \times 2 + 1}{2}$

3) Simplify 1 × 2 to 2.

$\frac{2t}{3} \times \frac{2 + 1}{2}$

4) Simplify 2 + 1 to 3.

$\frac{2t}{3} \times \frac{3}{2}$

5) Cancle 3.

$2t \times \frac{1}{2}$

6) Cancle 2.

$t$
