Well it's the same as normal exponents so you multiply 2/3 x 2/3 x 2/3 x 2/3 x 2/3
The answer is: " 2 :5 " ; or, write as: " 2/5 " .

The ratio of 'girls' to 'all students' is: "2: 5 " ; or, write as: " 2/5 ".

Given: The ratio of boys to girls is: " 3:2 " .
Problem: Find the ratio of "girls" to "all students:
________________________________________________________
Note: This ratio of "boys to girls", which is " 3 : 2 " ;
________________________________________________________
→ can be expressed as " 3x: 2x" ;
in which the total number of students is: " 3x + 2x " = 5x " .
→ The total number of students is represented as: " 5x " .
________________________________________________________
→ The ratio of "girls to boys" is: "2x : 3x" .
→ {that is; the "inverse" of the ratio of "boys to girls"} ;
→ {that is; the "inverse" of " 3x: 2x" } ; → which is: " 2x : 3x " .
________________________________________________________
The ratio of "girls" to "all students" is: "2x : 5x " ; or " 2x/5x " ;
→ Both "x" values cancel ; {since: " x/x = 1 "} ;
_________________________________________________________
→ and we have the answer: " 2 :5 " ; or, write as: " 2/5 " .

The ratio of 'girls' to 'all students' is: " 2 :5 " ; or, write as: " 2/5 ".

Well to find this answer, you want to divide $1.39 by 67.6. When you do this you get 0.0205. This is roughly 2 cents per ounce.
Answer: 3/16
Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.
× 
= ?
15 × 1 = 15
20 × 4 = 80
can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.
15 ÷ 5 = 3
80 ÷ 5 = 16
Therefore, × = 
The answer is 5 using the distance formula
