These 2 are correct.

$\displaystyle 14\% \times 35 = \frac{14}{100}\times 35 = 4.9$

$\displaystyle 48\% \times x = 12 \implies \frac{48}{100} \times x =12 \implies x = \frac{12}{0.48}$

It seems there are only 2 types of problem here. If you have used the same method on the rest as you did these first 2 you should be confident with your solutions.

3. Yeah I believe I did use the same method. So they should be all correct, yeah?

The first 2 are correct. I haven't checked the others. If you have used the same method for the others they should be correct.

Have a bit of faith!

5. I went through all of them, and you are correct for all of them.
