So first convert hours to minutes and we know that 1 hour is 60minutes.
So 1/5th of an hour would be one fifth of 60 mins right?
So to fnd what a certain fraction of a certain number is you have to multiply the numerator of the fraction by the number(60) and put it over the denominator (5).
So you get 1 multiplied by 60/5.Which is 60/5.
And we divide 60/5 to get 12.
So the answer is 12 minuets.
Hope this helps:)
Answer:
28
Step-by-step explanation:
42/15=x/10
*15 *15
42=15x/10
*10 *10
42*10=15x
420=15x
:15 :15
420/15=x
x=28
1800 cm: 20 m in its simplest form is 9cm : 10 cm
<h3>What is ratio?</h3>
Ratio says how much of one thing there is compared to another thing. Ratio compares value.
Therefore, let's make the unit the same.
0.01 m = 1 cm
20m =
length = 20 / 0.01
length = 2000 cm
Therefore, the ratio is as follows:
1800 cm : 2000 cm
Let's write it in it simplest form.
1800 / 2000 = 9 / 10
Therefore, the simplest form is 9 cm : 10 cm

When x=6
=>y=1/3*6+2=2+2=4
Answer:
27
Step-by-step explanation:
r = 9
s = 6
r^2
= r x r
= 9 x 9
= 81
13s
= 13 x 6
= 108
13s - r^2
= 108 - 81
= 27
