I GOT YOU.
First things first,
When multiplying fractions, it's super super super simple. Just multiply the numerator and denominator across, then simplify if needed!
________________________________
To solve your problem,
1. multiply the numerator across.
3 x 4 x 7 = 84
2. multiply the denominator across.
5 x 2 x 3 = 30
3. now you have the fraction \frac{84}{30}  (84/30 if you're on mobile)
4. simplify
84/30 has a common factor of 6. So it simplifies to 14/5.

Your answer is 14/5

Which step is incorrect and what is the correct answer?
Anit [1.1K]

Answer:

Step 4, x = 3

Step-by-step explanation:

Step 4 was wrong, instead of 6x = 6, it should be 6x = 18. They shoudl've added 6 to both sides instead of subtracting 6 as ur trying to cancel out the 6 on the left side of the equation. So:

6x = 18

x = 3

Given a and b are numbers, and a + b = 180, which

If the first one is a = 180 - b, and not 180 - 6, then that is correct.

Also, 360 = 2a + 2b is correct

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = 5*10^5

Number of viruses = 2*10^9

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

2*10^9=(5*10^5)x

Dividing both sides by 5*10^5

\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000

The number of viruses was 4000 times greater than number of protozoa.
