Answer :
Harry can first substitute 30 for t
He can then multiply [tex]\frac{1}{3}[/tex] by 30 to get a product of 10
Since, 10 is not equal to 15, Harry's solution is not correct.
Solution:
Given that,
Harry solves the equation:
[tex]\frac{1}{3}t = 15[/tex]
He says the solution is 30
We have to check if his answer is correct or not
Fill in the blanks to explain how Harry can check whether his solution is correct
Harry can first substitute 30 for t
[tex]\frac{1}{3} \times 30 = 15[/tex]
He can then multiply [tex]\frac{1}{3}[/tex] by 30 to get a product of 10
[tex]10\neq 15[/tex]
Since, 10 is not equal to 15, Harry's solution is not correct
Correct solution:
[tex]\frac{1}{3}t = 15\\\\t = 15 \times 3\\\\t = 45[/tex]
Thus correct solution is 45
