This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below. Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction Step 2: 100 times 12 = 1200 Step 3: 150 times 12 = 1800 In what step did Martin make a mistake, if any? Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.

Step-by-step explanation:

Given This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week.

Step 1 : part / whole = 150 / 100 = ? / 1200

Step 2 : 100 x 12 = 1200

Step 3 : 150 x 12 = 1800

In what step did Martin make a mistake if any?

Step 1 : Martin should have written his ratio as 1200 / ?

Step 2 : Martin should have divided 1200 by 8

Step 3 : Martin should have added 1200 and 150

Martin did not make any mistakes.

Let this week be denoted by a and last week be denoted by b
So a / b = 1200 / ?
Now 1200 / ? = 150 / 100
So 150 x 8 = 1200, so we need to multiply both numerator and denominator by 8 and so the fraction will be equal on both sides.
Now 1200 / ? = 150 x 8 / 100 x 8
So 1200 / 800 = 1200 / 800
So Martin makes a mistake in step 1. It should have been 1200 / ?
