Bess has knitted 5/8 of the she is making has knitted more than 1/2 of the scaft

Would love to help but I don't understand your question. Sorry

Let the number be x,y and 43
y-x=10
thus
y=10+x
the sum off the numbers will be:
x+y+43=79
plugging the values we get:
x+(10+x)+43=79
solving for x we get:
2x+53=79
2x=79-53
2x=26
x=26/2=13
hence:
y=10+13=23
thus the numbers are 13,23 and 43
the product of the number will be:
13×23×43
=12,857

12,857
