Answer:
296 and 22
Explanation:
111/6 = 18.5 according to the chart given, so
x/16 = 18.5.
Multiply both sides by 16 to isolate x.
x = 296
check work:
296/16 = 18.5
do the same to 407:
407/x = 18.5
Mulitply both sides by x.
407 = 18.5x
divide both sides by 18.5 to isolate x.
22 = x
check work:
407/22 = 18.5
