- If x is the number, then
x*7/18 = x*7/8 -770
x/18 = x/8 -110
x/8-x/18 = 110
5x/72 = 110
x= 72*110/5= 72*22= 1584 - 13 years agoHelpfull: Yes(67) No(0)
- diff of result is 770
diff of multipliers is 7/8-7/18= 35/72
hence if no is x then 35x/72=770
or x= 1584 - 13 years agoHelpfull: Yes(7) No(0)
- suppose no is x soo x7/8 -x7/18 ====770
sooo x===1984 - 13 years agoHelpfull: Yes(0) No(16)
- let no be y
7y/18=x-770
7y/8=x
7y/18=7y/8-770 solve it we get
y=792 - 13 years agoHelpfull: Yes(0) No(12)
