Words to Symbols and Vice Versa

How can I figure out word problems and math in real life?

Are you good at translating?

• Let’s try a few translations

• The sum of a number and 12 is 16

• x + 12 = 16

• The quotient of 15 and a number is less than 3

• 15/x <3

Use the translation to solve real problems

• You make a long distance call that costs \$0.10 a minute. You spent \$5.00. How many minutes did you talk?

• Cost of call = \$0.10 per minute

• \$5.00 = \$0.10x

• \$0.10 \$0.10

• 50 = x

• You talked 50 minutes
