5/9=x/27 135=9x 15=x
X/27 = 4 Multiply both sides by 27: X = 4*27 = 108
x2 = 9, 3 x 9 = 27, 27 - 4 = 23
Here are two ways you can find the answer in your head: I don't really know my 27 times tables very well, but I know that 27 is 3 x 9, and 4 x 3 is 12, and I do know my 12 times tables, so I take the 3 from the 27 and multiply it by the 4. 4 x 27 = 4 x 3 x 9 = 12 x 9 = 108 The other way is to change 27 into 25 + 2 and multiply each addend by 4. 4 x 27 = 4 x (25 + 2) = (4 x 25) + (4 x 2) = 100 + 8 = 108
(3 x 9) + (4 x 9) = 7 x 9 = 63
4/9 of 27 = 4/9 x 27 = (4 x 27)/9 = 12
4 over 27
5/9 ÷ 15/4 = 5/9 x 4/15 = 4/27
108 (4 x 27, 27 x 4, 12 x 9)
make lower number the same so 4 x 9 = 36 then 3/4 x 9/9 = 27/36 and2/9 x 4/4 = 8/36 so 27/36 - 8/36 = 19/36
3/4 x 9/21 = 27/84 = 9/28
243/50 or 4 and 43/50
5/9=x/27 135=9x 15=x
X/27 = 4 Multiply both sides by 27: X = 4*27 = 108
1/9 x 27 = 3
3/9 = x/81 x = 27 So: 3/9 = 27/81
3/4 - 2/9 make the base the same 4 x 9 = 36 so 3/4 =27/36 2/9 = 8/36 then 27/36 - 8/36 = 19/36
