Answer:
b=7/33 c= 14/33
Step-by-step explanation:
Repeat all 21 they are repeating decimals
for b its 100x-x=21.21 repeating the 21 -0.21 repeating the 21 = 100x-1x=(21+0.21)-0.21= (100-1)x=21+0.21-0.21 [ stop repeating the 21's up to here] and 99x=21+0 = 99x=21 = 99x/99=21/99 both 99's cancel leaving 3x7 divided by 3x33 = x= cancel both 3's leaving 7 over 33 This should help you learn to solve c good luck
