Write four different ratios to describe the red and green apples. Write the simplified ratio of green to red apples.
Part to part - 3:9, 9:3
Part to whole - 3:12 and 9:12
Green to red = 3/9 Simplified = 1/3

On a vertical number line where 0 represents sea level and each line represents 1 meter, a cat fish is marked at -3. Use absolute value to talk about the position of the fish.
The cat fish is 3m below sea level.

Write the coordinates of this point and write a statement about the scale being used for each axis.
The coordinates are (12,4). The scale for x is each step = 3. The scale for y is each step = 1

After a birthday party, there are 6 slices of a cake left. This is 2/3 of the original cake. How many slices did the cake have orginally? Bonus question: what TYPE of division is this?
6 pieces IS 2/3 of the cake so 6÷2/3 is the way to work it out. There were 9 pieces originally.
Bonus: it is partitive division as we are using the word IS.

What is the distance between two points that have the coordinates (0, -18) and (0, 5).
23 units

What is 3/5 ÷2/10? Work it out twice showing you know BOTH the methods for dividing fractions.
Method 1 - keep, change, flip
Method 2 - same denominator
It is 3.
Method 1 - 3/5 x 10/2 = 30/10 = 3
Method 2 - Double the first fraction to make the same denominator 6/10 ÷2/10 = 6/2 =3

Divide 1.50 by 0.25.
6 (you should have multiplied both by 100 to create whole numbers before divding).
1.50/ 0.25 x 100/100 = 150/25
