99 x 9 = 891
One possibility: 9 + 99/99 = 10
It is simple. 99 + 9/9 = 100!!!
An equation is any string of variables that 'equates' to a value:x + 9 = 10Technically the only number here is 9 :)An expression that equals 10 but only uses the number nine is:(9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9) / 99/9+9=10
Because 9*11 equals 99
20
It equals 22/99 and 11 goes in both of the numbers so it is now 2/9.
it equals 1
There are lots of ways to do this, but here's one:(99 - 9) / 9 = 10By the way, you probably mean "expression" rather than "equation." The equation includes both sides of the equals sign, so it isn't written only with 9's.
99
h/9=7 multiply both sides by 9 h=63
99 + 9/9 = 99 + 1 = 100
36 divided by 9 equals 4
