Assuming you mean four-ninths of 72, you should initially work out one-ninth - which is 72/9= 8. Then multiply your answer for one-ninth by four, to get the answer for four ninths: 8 x 4= 32.
32
30 :)
40/72 + 27/72 = 67/72
2/9 of 72 = 16
99/72 - 64/72 = 35/72
2/9 minus 1/8 is 7/72
(4/9) x 72 = 4 x 8 = 32
It is: 8/9 of 81 = 72
6 and one ninth = 55/9, 1 and five eigths = 13/8. LCD is 72 so 440/72 - 117/72 = 323/72 = 4 and 35/72
There are nine parts of the whole to form ninths. Therefore: 9 x 8 = 72 (72/9 seventy-two over nine).
