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)

— = —

(7) (7)

84

x = —

7

x = —

7

Simplify.

x = 12

Remember that you're solving for a dollar amount.

$12

Hi Tami;

($42)(2/7)

This is also...

($42/1)(2/7)

Let's multiply the numerators, numbers on top, together...

($42)(2)=$84

Let's multiply the denominators, numbers on bottom, together...

(1)(7)=7

$84/7

$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.

$42 * 2/7 = $12
