Answer 3

write 72=9*8
and 27=9*3

Answer 4

for example

Answer 5

Yes, you need to convert it to a fraction first.

Answer 6

.72 repeating = 72/99
.27 repeating = 27/99

Answer 7

why

Answer 8

The way to convert a repeating decimal can be done as follows:
For the repeating decimal 6.36 (where the digits 36 repeat forever) can be expressed as decimal:
6+36/99=6+4/9=\(6\frac{4}{9}\).
Similarly, if all six digits following decimal point repeat,
5.142857=5+142857/999999=\(5\frac{1}{7}\),
and so on.
So convert the two repeating decimals to fractions and simplify.

Answer 9

The explanation for
0.36(repeating)=36/99 is as follows:

x=0.36(repeating) ...........(1)
100x=36.36 (repeating)..........(2)
(2)-(1)
99x = 36
x=36/99

Answer 10

@Mathmate is correct. When dividing, multiplying, adding, or subtracting repeating decimals you must convert it to a fraction first

Answer 11

When dividing two fractions,you need to flip the second fraction and multiply by the reciprical.

Answer 12

oh ok thanks

Answer 13

\[x=\frac{ 0.727272... }{ 0.272727... }=\frac{ 727272... }{ 272727... }=\frac{ 72\left( 0.101010.... \right) }{ 27\left( 0.101010... \right) }\]\[=\frac{ 72 }{ 27 }=\frac{ 8 }{ 3 }=2\frac{ 2 }{ 3 }\]

Answer 14

0.72 divided by 0.27 equals 2 2/3 because 0.72= 72 and 0.27=27 so it is 72 divided by 27 which is 8/3 of 2 2/3

Answer 15

i meant 8/3 or 2 2/3
