1. Add all even numbers between 31 and 37.

2. If a 250-L tank is 7/10 full, how much more could it hold.

3. Which is larger, 77.7 or 77 7/100?

4. Decrease 1 426 231 by 400 000.

5. How many 2-cm cubes could fit into a box with length 8 cm,

width 4 cm and height 10 cm?

1. 32+34+36=102

2. 250/1*7/10=1750/10 = 175

250-175 = 75 more gallons

3. 77.7, 77 7/100 = 77.07 so 77.7 is larger

4. 1,026,231

5. 16 cubes, 4 each way because 8:2=4 and 4^2 is 16

6 1/4 cubes for 4cm because area of 4cm cube is 16 and area of 10 cm is 100, and 100:16=6.25 or 6 1/4
