7x4 equals 28.
I remember this as " is over of equals per cent sign over 100." 700/2500=%/100 Divide 700 by 2500 and get .28. .28 is equal to 28%.
28 centimeters is equal to about 11 inches.
It equals 28.

Let the number 'm' & 'n' Hence # Multiplication mn = - 1344 Added m + n = 43 We have two unknowns , So we eliminate one of them . Hence mn = -1344 m = 43 - n Substitute (43 - n) n = -1344 43n - n^(2) = -1344 n^(2) - 43n - 1344 = 0 We now have quadratic eq;n to solve Hence n = { --43 +/- sqrt[(-43)^(2) - 4(1)(-1344)]} / 2(1) n = { 43 +-/ sqrt[ 1849 + 5376]} / 2 n = { 43 +/-sqrt[ 7225] } / 2 n = { 43 +/- 85}/2 n = 128/2 = 64 & n = - 42/2 = -21 Verification 64 X -21 = -1344 64 - 21 = 43 So the two numbers are '-21' & '64'.
There's only one number that equals 28. The number is . . . . . wait for it . . . . . 28.

30. 28 x 30 = 840
There is no prime number equal to 28. I know you must find this disappointing.
