Question

Harry solves the equation 1/3t=15. He says the solution is 30. Is his solution correct.

Answer 1

Answer:

Harry's solution is incorrect.

Harry can first substitute (30) for t. He can the multiply 1/3 by (30) to get a product of (10). Since 15 (≠) equal to (10), Harry's solution is (not) correct.

Step-by-step explanation:

Given:

Equation = $\frac{1}{3}(t) =15$

Solution of the equation = $30$

Lets check the equation whether both sides of the equation gives same result by plugging the values of t = 30.

⇒ $\frac{1}{3}(t) = 15$

⇒ $\frac{1}{3}(30) = 15$

⇒ $\frac{30}{3} =15$

⇒ $10=15$

We know that 10 ≠ 15 so the solution is incorrect.

According to the question :

Harry can first substitute (30) for t. He can the multiply 1/3 by (30) to get a product of (10). Since 15 (≠) equal to (10), Harry's solution is (not) correct.

Harry's solution is incorrect.
