<span>1/7 is the unit fraction or the simplest form of the given 12/84
Look into:
Equivalent fractions are fractions having the same value even if they look different. Look different means they may not have the same denominator or numerator but, when you multiply the top (numerator) and the bottom (denominator) by the same integer, the fraction keeps its value. </span>
<span> Equivalent fractions can be simplified and written as the same fraction for example, 18/27 = 6/9 = 2/3. </span>
<span>Example: </span>
<span>Two equivalent fractions of 8/24. </span>
<span>8/ 24 can also be 1/3. Why? How did it happen? </span><span>
Simply, get the GCF, the Greatest Common Factor or the GCD, Greatest common Divisor of both numerator and denominator.</span>
<span>8 = 1, 2, 4, 8 </span>
<span>24 = 1, 2, 3, 4, 6, 8, 12, 24 </span>
8 is the greatest common factor of 8 and 24 so,
<span><u>_8 </u>÷ <u> 8_ </u> = <u>_1_</u></span><span> </span><span>
24 8 3</span><span> </span>
8/24 is also equivalent to 2/6. Thus;
<span>8/24=2/6=1/3 <span>

Answer:
8100 ft^2
Step-by-step explanation:
area = Lengthx width
if its a square the length is 90 width is 90,
90x90 = 8100
Answer:
Step-by-step explanation:
6x - 6 = 7x - 8
-x = -2
x = 2
CJ= 6(2) - 6 = 12 - 6 = 6
JT= 7(2) - 8 = 14 - 8 = 6
6 + 6 = 12 for CT
angle at a straight line is =180
4+5+x=180
let x be angle at the tower
9+x=180
x=180-9
x=171°
and x is divide in to two then is 2x
there for
2x=171°
x=171/2
x=85.5°
then sin85.5°= 90/y
let y be the unknown feet
0.9969=90/y
y0.9969=90
y=90/0.9969
y=90.3ft.
