9
yes,9 goes into 81:9 times
Nine goes into 81 exactly nine times. This is because when you divide 81 by 9, you get 9 (81 ÷ 9 = 9). Therefore, the answer is 9.
0.1111
The two squared numbers that divide to make 9 are 81 and 9. When you calculate (81 \div 9), you get 9, and both 81 (which is (9^2)) and 9 (which is (3^2)) are perfect squares.
3 - 81
First divide 3 into 81 81 ÷ 3 = 27 so 81 = 3 × 27 Next divide 3 into 27 27 ÷ 3 = 9 so 27 = 3 × 9 and hence 81 =3 × 27 = 3 × 3 × 9 But 9 = 3 × 3 and thus 81 = 3 × 3 × 9 = 3 × 3 × 3 × 3 = 34
Divide both numbers by 9 (a factor of both 72 and 81) and you get 8/9
18/81 = 2/9 (divide top and bottom by the hcf of 18 & 81 = 9)
81/44 has a greatest common factor of 9; divide both top and bottom by 9 81/144 = 9/16
9 is the largest integer that can divide into both 36 and 81 evenly with no remainder.
Yes, these numbers: 1, 3, 9, 27, 81.
To solve the equation ( 9d = 81 ), divide both sides by 9. This gives ( d = \frac{81}{9} ), which simplifies to ( d = 9 ). Therefore, the solution to the equation is ( d = 9 ).
