Answer 6

hm :S usually using this method you're supposed to round each number to the nearest whole number before multiplying

Answer 7

3.8 rounds up to 4
9.5 rounds up to 10

making 4 * 10 my best attempt

i'm still not 100% sure this is the method they'd want though

Answer 8

it works

Answer 9

cool

Answer 10

they want you to round the numbers before multiplying

so 10.2 rounds down to 10
1.04 rounds down to 1

so 10.2 * 1.04 becomes 10 * 1
