2/9 divided by 12/3
What is 8/9
Invert the denominator fraction and multiply
(2/9 ÷ 3/12 = 2/9 * 12/3)
Multiply the numerators (2*12=24)
Multiply the denominators (9*3=27)
Place the product of the numerators over the product of the denominators (24/27)
Simplify the Fraction (24/27 = 8/9)
OR
after inverting you can do (2x12) divided by (9x3). Cancel the 12 and 9 (as both are divisible by 3) so you have
(2x4) divided by (3x3) which = 8/9

If it is +32°C in Florida and −10°C in Alaska, how much warmer it is in Florida than in Alaska.
Write in a numerical equation.
What is 42 degrees
The difference between the temperatures is

These are the 3 types of angles in geometry and their accompanying range of degrees.
What is an:
1- Acute angle (between 0-90 degrees)
2- Right angle (a 90 degree angle)
3- Obtuse angle (between 90-180 degrees)
500
These are the 3 consecutive odd numbers, the sum of which equal 33*
What is 9, 11, and 13
x + (x + 2) + (x + 4) = 33
3x + 6 = 33
3x = 27
x = 9
Therefore the three numbers are 9, 11 and 13
