To divide fractions: flip the second and multiply. 2/3 times 5/3 us 10/6 to 5/3, which is 1 1/3 0r 1.333333.
7/12 times 3/2 so 21/14 or 3/2 or 1 1/2 or 1.5.
For the mixed numbers, make them improper fractions. 14/3 times 1/7 or 14/21 or 2/3 or .666666.
21/5 times 5/7 so 105/35 or 21/7 or 3.
17/20 to a decimal, is easy, just change the bottom number to a number that fits into the decimal places by using a proportion. 17/20 = x/100. 20x = 1700 Divide both sides by 20. 85/100. .85.

To divide fractions, you multiply the first fraction by the reciprocal of the second. 1. 2/3 divided by 3/5 = 2/3 • 5/3 = 10/9 2. 7/12 divided by 2/3 = 7/12 • 3/2 = 7/8 3. 3 1/2 divided by 3/4 = 7/2 • 4/3 = 14/3 btw reciprocal is basically a fraction flipped over. :D

when you divide fractions just invert the second fraction and multiply
2/3 / 3/5= 2/3 x 5/3= 10/9=1 1/9
7/12 / 2/3= 7/12 x 3/2= 7/8
3 1/2 / 3/4 7/2 / 3/4 = 7/2 x 4/3= 14/3=4 2/3
14/3 /7= 14/3 x 1/7= 2/3
21/5 / 7/5= 21/5 x 5/7=3
17/20= .85

Here you go!
2/3 / 3/5 = 10/9
7/12 / 2/3 = 7/8
3 1/2 / 3/4 = 14/3
4 2/3 / 7 = 2/3
4 1/5 / 1 2/5 = 3
17/20 = 0.85
You should really learn to do these yourself though.

it is 9/10 because when you divide you can just flip the second fraction around and multiply and get your answer
