ANSWER
0.1
EXPLANATION
We want to estimate the quotient of 1.64 ÷ 22.
To do this, we will approximate the two numbers to whole number and solve it.
It becomes:
2 ÷ 20
That is:
Note: since 2 cannot be divided by 20, we write 0. and add a 0 to the back of 2.
The estimate of the quotient is 0.1.
Answer: 1/6
-1/2 also equals -3/6
2/3 also equals 4/6
Using the number line, start at -1/2. Then, since the distance from one dash to the next on the line equals 1/6, you will move 4 spaces to the right. That should give you 1/6.
