42 x 28 = 1176
28+14=42, But 28 x 14=392, Therefore the answer is NO!
28/42 x 100 = % Answer = 66.66666 recurring % = 67%

GCF of 28 42 and 56 is 14.The GCF is 14.(28 = 2 x 14, 42 = 3 x 14, 56 = 4 x 14)To find the GCF, factor the numbers and multiply their common prime factors:28 = 2 x 2 x 742 = 2 x 3 x 756 = 2 x 2 x 2 x 7Common factors are 2 x 7 = 14
150 (42/0.28) To answer a problem such as this use the formula: a % #/100 = is/of (a % # over '100' b/c the most you can have is 100%) [equation reads, "a percentage number over 100 equals 'is' over 'of'"] So in your case it would be: 1) 28/100 = 42/x (then you cross multiply which gives you): [you have the 'is' as your original question states "is 42." You are trying to find the 'of'] 2) 28x = 4200 (then divide 4200 by 28 to solve for x) x=150 Then to check your answer, plug 150 into the x in the original equation and make sure both sides equal each other. So: 28/100= .28 & 42/150= .28

The two partial products of 42 X 28 are 42 X 8 (336) and 42 X 2 (84). To get the actual answer, you shift the partial product (42 X 2) one decimal space to the left and add it to the other partial product, (42 X 8). 42 X 2 = 84. Now, shift 84 one decimal space to the left. This gives you 840. 42 X 8 = 336. Now add 336 to 840 to get the final result, 1176.
