Hi all.... that’s brill. Hadn’t looked at it that way.

That exam does lend itself to being compared, but are you able to do the same with:

4t + A = 265

T + A = 115

What is T and A?

These are the only examples I have been able to find so far. Trying to get my head wrapped around an easier way (other than using algebra - only way I know) to teach little one... more suggestions pls where not so easily comparable

For questions like these use common sense and forget Algebra.

The difference between the two totals is 3T.

The difference between the two totals is 150. So T must = 50, that is 150 divided by 3.

T + A = 115 so 50 + A = 115.

115 - 50 = 65 so A must = 65.

As Sookie says, this is spot the difference.

Where are you getting these questions from and what exams are you preparing for?
