6/7 divided by 12/14 please show the work
Minchanka [31]

Answer:

1

Step-by-step explanation:

When dividing one fraction by another, the best way to solve it is to multiply by the reciprocal. The reciprocal just flipping the fraction over. So you would leave the 6/7 and the multiply by 14/12( because you are multiplying by the reciprocal). When you do that, you then can just multiply the top and the bottom to form one fraction. The numerator is 6*14 = 84, and the denominator is 7*14 = 84. So you are left with 84/84 which anything over itself is equal to one.

Hope this helps!

AysviL [449]

Answer:

A. 1,825 days

B. 56 days

C. 1 week

D.  1,209,600 seconds

E. 43,200 seconds

F. 2 hours

Step-by-step explanation:

A. 1 year = 365 days, then

5 years = 5\cdot 365 days = 1,825 days.

B. 1 week = 7 days, then

8 weeks = 8\cdot 7 days = 56 days.

C. 7 days = 1 week.

D. 1 hour = 3,600 seconds, then

336 hours = 336\cdot 3,600 seconds = 1,209,600 seconds.

E 12 hours = 12\cdot 3,600 seconds = 43,200 seconds.

F. 3,600 seconds = 1 hour, then

7,200 seconds = \dfrac{7,200}{3,600} hours = 2 hours.
