224 8 x 28 (2x4) x (4x7) (2 x (2x2)) x ((2x2) x 7) Since 2 and 7 are prime numbers, the factor tree is complete.
800 It's basic leaves two zeros 2x4=8 8+00=800 Look closely don't ask this QUESTION!
80
1 3 / x / 2 4 Multiply the numerators and then the denominators Numerators: 1x3 =3 Denominators: 2x4 =8 So the answer is 3/8 which is 3 ovr 8
If you mean '2x4' as in 2 times 4- 2x4= 8 3x3= 9 4x2= 8 8-9-8=-19 if you want to divide by x -b/c x doesn't have a set amount- it would be: -19/x
Take the sum in stages.2x4 is 8.8-8 is 0.
