5 0

Step-by-step explanation:

step 1. 17/21 - 2/10 = x (in order to subtract you need a common denominator)

step 2. (17/21)(10/10) - (2/10)(21/21) = x

step 3. 170/210 - 42/210 = x

step 4. 128/210 = 64/105 = x

step 5. x = 64/105.

The common denominator is 32

1/8 multiply by 4/4 =. 4/32

Smallest to greatest is 1/8. 3/16. 11/32. 3/4
