Answer:
72 km/h
Step-by-step explanation:
We need to convert units
so:
20 m ----- 1 km -------- 3600 s
1 s ----- 1000 m ----1 h
and solve ot
20 x 1 x 3600 s = 72000 we multiply numerators
1s x 1000 m x 1 h = 1000 we multiply denominators
we divide de results 72000/1000 = 72

<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>
</span></span>
