10 x 28 = 280
28 ft * 10 ft = 28*10 = 280 square feet.
28-18=10 or 18-28= -10
If it is (4 x 10) - 3 = 37 If it is 4 x (10 - 3) = 28
10/28 = X/XXVIII
10 x 28 = 280
The partial products of 28 x 14 are 112 and 280. 28 = 8 + 20 ⇒ 28 x 14 = 8 x 14 + 20 x 14 = 112 + 280 14 = 4 + 10 ⇒ 28 x 14 = 28 x 4 + 28 x 10 = 112 + 280 The partial products are the same in the different splits as 28 = 2 x 14. If the numbers had been, say, 17 x 28 then: 28 = 8 + 20 ⇒ 28 x 17 = 8 x 17 + 20 x 17 = 136 + 340 17 = 7 + 10 ⇒ 28 x 17 = 28 x 7 + 28 x 10 = 196 + 280
28 ft * 10 ft = 28*10 = 280 square feet.
28-18=10 or 18-28= -10
The first ten positive integer multiples of 28 are: 1 x 28 = 28 2 x 28 = 56 3 x 28 = 84 4 x 28 = 112 5 x 28 = 140 6 x 28 = 168 7 x 28 = 196 8 x 28 = 224 9 x 28 = 252 10 x 28 = 280
If it is (4 x 10) - 3 = 37 If it is 4 x (10 - 3) = 28
10/28 = X/XXVIII
28 = (2 x 10) + (8 x 1)
If the number, x, has 10 subtracted from twice it to make 28, then x must be 19. 2x - 10 = 28 2x = 38 x = 19
There are 10 centimetres in one decimetre. Therefore, 28 decimetres is equal to 28 x 10 = 280 centimetres.
2.8 x 10= 28 26 x 100= 2600 Therefore 2600>28, 26 x 100 is the greater of the two equations
28 + 19 + 10 = 57 inches.
