What is the answer to adding 3/14 1/7
sp2606 [1]

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>

ankoles [38]
10*3=30
30*3=90
90*3=270
270*3=810

or

10*3^1=30
10*3^2=90
10*3^3=270
10*3^4=810

the next two terms of this sequence are 270 and 810.

1. What is the probability of an odd outcome?
Xelga [282]

Answer:

1. 50%

2.\frac{5}{6}

Step-by-step explanation:

1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.

2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.

P = N / NP

Dice has 6 faces. I.E. 1,2,3,4,5,6

= 6

NP, therefore, is the total number of possible outcome.

Faces less than 6. (1,2,4, and 5)

N = 5

P = N / NP = \frac{5}{6} ; it can't be reduced.
