Which simplified fraction is equal to 0.53 with bar?

Oxana [17]

I assume that 0.53 with a bar means the decimal fraction in which 3 is repeating.

24/45, 8/15, and 48/90 all result in the same decimal value. Thus, we are simply looking for the one that is fully simplified.

The correct answer is 8/15.

Hope this helps!

<u>Answer:</u>

The correct answer option is $\frac { 4 } { 4 9 }$ .

<u>Step-by-step explanation:</u>

We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = $7$

Number of days in weekend = $2$

Probability of being born on weekend = $\frac { 2 } { 7 }$

P (both parents were born on weekend) = $\frac{2}{7} \times \frac{2}{7}$ = 4/49
