    These 2 are correct.

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

    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.

    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!
