If six chocolate bars cost £3. 80 how much is for 5

5 chocolate bars cost 3.15 (i don't have that currency symbol on my keyboard)

Step-by-step explanation:

First, let's find out what one costs, so it'll be easier.

3.80/6=0.63

Multiply the amount for one chocolate bar by five:

0.63*5=3.15

And there you go! 5 bars cost 3.15

I hope this helped!

 £4.56

Step-by-step explanation:

5 chocolate bars= £3.80

1 chocolate bar= £3.80 / 5 = £0.76

Therefore, 6 chocolate bars= £0.76 x 6 =  £4.56

goog may be able to you find that answer

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
