3 2/7 minus (1 6/7 +2/5) =
poizon [28]
First, let's make all the mixed fractions into improper fractions. To do that, we multiply the whole number by the denominator and add the numerator; this new number becomes the numerator while we keep the same denominator, thus:

3 2/7 = 3 * 7 + 2 / 7 = 21 + 2 / 7 = 23/7
1 6/7 = 1 * 7 + 6 / 7 = 7 + 6 / 7 = 13/7

Our new problem is

23/7 - (13/7 + 2/5)

The next step to be able to simplify this is to have common denominators. To do that here, we will multiply the first two fractions by 5/5 and the third fraction by 7/7, thereby making all three fractions have a denominator of 35:

5/5(23/7) - [5/5(13/7) + 7/7(2/5)]
115/35 - (65/35 + 14/35)

Finally, we can add the fractions in the parenthesis, and then subtract that number from 115/35:

115/35 - 79/35
36/35

Answer:
36/35

A survey has a margin of error of +/- 4%. In the survey, 67 of the 110 people interviewed said they would vote for candidate A.
frozen [14]

Answer:

option B

Step-by-step explanation:

given,

sample of person interviewed 110

people voted for A = 67

percentage of the person voted for A = \dfrac{67}{110}

                                                                 = 0.609

now, for all the people

   = 0.609 x 9570

   = 5829 people

now compensating the error

+ 4 % = 1.04 x 5829 = 6062 people

- 4 % = 0.96 x 5829 = 5596 people

so, the range of people voted for candidate A is

5596 to 6062 People

Hence, the correct answer is option B
