To do this problem, you set up a proportion: 50 percent of 100 is equal to what (x) percent of 70? It should look like this: 50/100 = x/70 To solve this problem, divide 50 by 100: .5 = x/70 To finish the equation, times both sides by 70: (.5)(70) = (70)(x/70) [The x70 and /70 cancel each other out] 35 = x So, 50% of 70 is 35.

117. First, find the prime factorization for 234 and for 585. It may be helpful to include all prime numbers up to the highest factor in the listed factorization, even if a particular prime number has to be listed as to the zero power: 234 = 2 x 32 x 13 = 21 x 32 x 50 x 70 x 110 x 131 585 = 32 x 5 x 13 = 20 x 32 x 51 x 70 x 110 x 131 Then, to find the greatest common divisor, take each factor the fewest number of times that it appears in either factorization. So the greatest common factor will include 20, 32, 50, 70, 110, and 131. The greatest common factor is thus 20 x 32 x 50 x 70 x 110 x 131 = 117.

50 x 70 x 2 = 7000

70 + (5 x 8) = 110

70. 100% of 50 is 50, right? so then you just find 40% of 50 (50 x 0.4 = 20) and add 20 and 50 to get 70

50 = 2 x 52 110 = 2 x 5 x 11 To find lc use highest power of each primer across the numbers, thus: LCM = 2 x 52 x 11 = 550

Percentage increase from 50 to 70 is (20/50) x 100 = 40% Percentage decrease from 70 to 50 is (20/70) x 100 = 28.5714%

Supplementary angle means that the sum of two angles should be 180o Let the required supplement be x x+110=180 x=180-110 x=70 Hence the required supplement of the 110 angle is 70 degree.

20 is the answer A+

50 is half of 100; 50 x 2 = 100 35 x 2 = 70 answer is 70%
