2015年9月10日 · 12 -: 1/3 = 12 * 3/1 = 36 In general, you can divide by a rational expression by multiplying by the same expression with numerator and denominator swapped.

2018年3月20日 · 1/4 We want to simplify using common divisors. We know that 3 is prime, so it can only be written as 1*3. We know that 12 is composite, so it can be written as 1 * 2 * 2 * 3.

2018年3月28日 · => x = -24 =>x/12 +1/3 = -5/3 First, we subtract 1/3 from each side: =>x/12 +1/3 - 1/3 = -5/3 - 1/3 => x/12 = -6/3 => x/12 = -2 Now we multiply both sides by 12: =>x ...

2017年8月4日 · Which method do you use to factor #3x(x-1)+4(x-1) #? What are the factors of #12x^3+12x^2+3x#? How do you find the two numbers by using the factoring method, if one number is seven more than...

2016年6月15日 · =7/12 When adding fractions, the denominators have to be the same before you can add the numerators. Find equivalent fractions for both 1/3 and 1/4 The lowest number which 3 and 4 can both divide into is 12 1/3xx4/4 = 4/12 " and " 1/4 xx 3/3 = 3/12 We can write this easier like this: 1/3 +1/4 =(4+3)/12 =7/12 " ONLY add the numerators"

2016年7月14日 · It’s not easy being a teenager. On top of huge biological and social changes, your future depends on doing well at school, and that’s hard. Every day, after 7 hours of school, you’re asked to do 3 hours of homework.

2017年8月30日 · S_n = (12(1-(-3)^n))/4 The sum to n of a geometric series, denoted as S_n, is given by the formula S_n = (a(1-r^n))/(1-r where a is the first term of the series and r is the common ratio.

2015年6月26日 · 1/3 is a rational number, being a number of the form p/q where p and q are integers and q != 0. It is not a natural number, whole number or integer. Numbers can be ...

2018年5月28日 · 1 2/3 Break the question up into two parts. Firstly, you are subtracting 3 from 5, which has an answer of 2. From that, you have the additional 1/3. Therefore, you subtract 1/3 from 2, giving you 1.bar(6) or 1 2/3.

2015年12月30日 · a_2/a_1=12/4=3 a_3/a_2=36/12=3 implies common ratio=r=3 and the given sequence is geometric sequence. Nth term of a geometric sequence is given by a_n=a_1r^(n-1) Where a_n is the nth term, a is the first term and n is the number of terms. Here a_1=4 and r=3 Put n=12 implies a_12=4*(3)^(12-1)=4*3^11=4*177147=708588 implies 12th term is 708588. Sum of geometric series is given by Sum=S=(a_1(1-r ...
