4 times 2
5 times 1
5 times 2

4 times 2

Step-by-step explanation:

4.25 can be rounded down to 4, and 1.95 can be rounded up to 2, which gives us 4.25 x 1.95 rounded to 4 x 2.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

triangle and cube
