Answer:
5/12
Step-by-step explanation:
change 1 1/4 to improper fraction:
1 1/4=5/4
find common denominator: 12
5/4=15/12
5/6=10/12

Hello There!
The answer to adding 3/14 and 1/7 together give you a sum of 5/14
STEP #1 <em>The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.</em>
STEP #2 Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
<h2>(3/14*1/1) + (1/7*2/2)</h2><h2 /><h2><em>3/14 + 2/14 = </em><u>
<em>5/14</em></u></h2>
Answer:
8/35 is correct
Step-by-step explanation:
Just multiply the numerator by numerator and denominator by denominator, then simplify
Answer:
cos(x-30)=1/2
Step-by-step explanation:
We use the following relationship to obtain cos(x)

From that, we have that cos(x)= sqrt(1-1/4)=sqrt(3) / 4
To obtain the value of cos(x-30), lets remember the following expression:

Therefor, we can use that to obtain our desired function cos(x-30)
cos(x)*cos(30)+sin(x)*sin(30)

=2/4=1/2
