Solve each proportion. Where necessary, round to the nearest tenth.

4/3 = b/21
I know b=28
do I round to the nearest tenth or what?

  • math -

    28 is a whole number, so b = 28.

    Your instructions say round where necessary. It's not necessary here.

  • math -

    (4/3)=(b/21) Multiply with 21
