3 x 30 = 90
3 x 3 = 9
90 - 9 = 81 = 3 x (30 - 3) = 3 x 27
81=3*3*3*3
81 has 5 factors: 1, 3, 9, 27, and 81.
There are 3 feet in one yard. Therefore, 81 feet is equal to 81/3 = 27 yards.
Because 3 feet is equal to one yard, and 81/3=27, there are 27 yards in 81 feet.
To determine how many times 27 goes into 81, you would divide 81 by 27. The result of this division is 3, indicating that 27 goes into 81 three times without any remainder. This can be calculated by dividing the dividend (81) by the divisor (27) to find the quotient (3).
FIve: 1, 3, 9, 27, 81
3 x 30 = 90 90 - 3 - 3 - 3 = 81 = 3 x 27
The multiples of 81 are infinite. The factors of 81 are: 1, 3, 9, 27, 81.
There are infinitely many different choices of 3 numbers that add up to 81. 50 + 30 + 1 = 81 40 + 40 + 1 = 81 10 + 11 + 60 = 81 etc.
LCM of 81 and 3 is 81.
If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...
