See if you can solve these word problems. Show how you worked it out!! (use brackets to expand numbers)

1. It rained 1.35 inches on Saturday and 1.98 inches on Sunday. How much did it rain on Saturday and Sunday combined?

• 1.35 + 1.98 = 3.33
• (1 + 1 = 2)

• (.5 + .8 = 1.3)

2. There were 7.6 litres of water in Jacob's bathtub. Then 2.9 litres drained out. How much water is left in the bathtub?

• 7.6 - 2.9 = 4.7
• (7 - 2 = 5 )
• ( .6 - .9 = .3)

3. A carpenter bought a piece of wood that was 6.15 meters long. Then he sawed 2.14 meters off the end. How long is the piece of wood now?

• 6.15 - 2.14 = 4.01
• (6 - 2 = 4)
• ( .10 - .10 = .0)
• ( .5 - .4 = .1)

4. A chef bought 4.2 kilograms of almonds and 7.8 kilograms of pecans. How many kilograms of nuts did the chef buy in all?

• 4.2 + 7.8= 12.
• ( 4 + 7 = 11)
• (.2 + .8= 1)

5. It snowed 8.9 inches on Monday and 3.9 inches on Tuesday. How much did it snow on Monday and Tuesday combined?

• 8.9 + 3.9= 12.8
• ( 8 + 3= 11)
• (.9 + .9= 1.8)

6. It rained 0.97 cm on Monday. On Tuesday, it rained 0.4 cm less than on Monday. How much did it rain on Tuesday? READ CAREFULLY-THIS ONE WILL TRY AND TRICK YOU!

• 0.97 - 0.4=  0.57
• (0.9 - 0.4 = 0.5)
• ( It rained 0.57cm on Tuesday.)

7. Omar spent Saturday picking berries at a berry farm. In the morning, he picked 3.61 kg of berries. In the afternoon, he picked 2.4 kgs. How many pounds of berries did Omar pick in all?

8. A bee colony produced 0.91 pounds of honey, but bears ate 0.9 pounds of it. How much honey remains?

• 0.91 - 0.9= 0.01
• (0.9 - 0.9 = 0.0)
• (0.1)

9. Oscar bought 5.87 pounds of melon and 3.18 pounds of cherries. How much fruit did he buy in all?

• 5.87 + 3.18= 9.05
