Cross-multiply to solve.
x        2
—  =  —
42      7

(7)x = 2(42)

7x = 84

Isolate x by dividing both sides of the equation by 7.

7x       84
—   =  —
(7)      (7)

84
x  =  —
7

Simplify.

x = 12

Remember that you're solving for a dollar amount.

\$12

Hi Tami,

John makes \$42.00 for a full day of work.

He works 2/7 of a day =2/7×42

=2×6=12

So he will make \$12 if he works 2/7 of a day.
