inna [77]

Answer:

Confused as well

Step-by-step explanation:

If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute

at 6 pm there would be 18 hours gone in the day

18 normal hours are equal to 18*60*60 = 64800 seconds

(64800 seconds) / 10000 ( for hours)

6:48 would be the replacement  time

but this answer is wrong bc it's not an option

Which of the following is a proportion?
poizon [28]

Answer:

Option C, 14/21=9/21 is the proportion.

Step-by-step explanation:

Given:

a.5/7 = 10/12

b.9/15 = 12/18

c.4/6 = 8/12

d.14/21 = 9/12

We have to find the proportions.

In proportion two ratios are equal, as it has an equality sign in between so both side must be of same ratio in its simplest form.

Let's work with option C

⇒ \frac{4}{6}=\frac{8}{12}

To find the simplest form we have to divide the numerator and denominator with same digit (or its factor).

Simplest form of  \frac{8/2}{12/2} = \frac{4}{6} , \frac{4/2}{6/2}= \frac{2}{3}

Simplest form of \frac{4}{6} = \frac{2}{3}

Both sides in option C have equal ratios of 2/3.

So 4/6=8/12 is in proportion.
