Which is greater, 7/8 or 13/16? explain.

To compare these fractions, bring them to the same denominator. Expand the fractions to bring them to the common denominator (LCM):

7/8 = (2 * 7) / (2 * 8) = 14/16

13/16 = (1 * 13) / (1 * 16) = 13/16

Same denominator fractions sorted ascending:

13/16 < 14/16

Initial fractions in ascending order:

13/16 < 7/8

Step-by-step explanation:

7/6 is bigger its a 1 number away from being a full and 13/16 is just a 1/2 full.

ryan had a head start of 10 meters.

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.
