Pep Club members are making spirit buttons. They make 490 spirit buttons in LaTeX: 3\frac{1}{2}3 1 2 hours. Find the number of buttons the Pep Club makes per hour. How many buttons do the members make per hour?

140 Spirit buttons per hour

Step-by-step explanation:

From the above question:

3 1/2 hours = 490 spirit buttons

1 hour = x spirit buttons

Cross Multiply

3 1/2 hours × x = 1 × 490 Spirit buttons

x = 490 spirit buttons/ 3 1/2 hours

x = 490 ÷ 3 1/2

x = 490 ÷ 7/2

x = 490 × 2/7

x = 140 Spirit buttons

Hence, the Pep club members make 140 Spirit buttons per hour
