Valek finds the distance between P and R. His work is shown below.

Step 1   32/48 = 20/PR

Step 2   20PR = (32) (48)

Step 3    20PR = 1,536

Step 4    PR = 76.8 km

What is Valek’s first error?

Valek did not correctly divide 1,536 by 20 going from step 3 to step 4.

Valek did not find the correct product of 32 and 48 going from step 2 to step 3.

Valek should have written the proportion in step 1 as 32/20 = PR/48.

Valek should have written the cross-product in step 2 as 32PR = (20) 48).

We have been given work of Valek to find the error if any.

There is no question or word problem which is used to make equation so step 1 is correct without any question.

Then he did cross product and got 20PR=(32)(48) while correct cross product will be 32PR = (20) 48).


Hence the last choice "Valek should have written the cross-product in step 2 as 32PR = (20) 48)." will be the final answer.
