Answer:
Answer to the 1st question is: 16/9 or 16:9 (whichever form you use)
Answer to the 2nd question is: 7/9 or 7:9
Step-by-step explanation:
<u>Key skills needed: Number theory, Ratios, and Fractions</u>
1) Let's look at the first question. A ratio is usually a number of something over a number of another thing. One such example is 5 apples : 4 oranges (or 5 apples/ 4 oranges - whichever form you write in).
- Based on that let's look at the first problem. We want to find the ratio of all the marbles in the bag to the blue marbles. So it would be --> the total # of marbles over the number of blue marbles.
- The total number of marbles is 7+9= 16. This would be our <u>first number, or the numerator. </u>
- The number of blue marbles is 9. This would be our <u>2nd number, or the denominator of the ratio.</u>
- With this information --> The ratio would be 16/9 or 16:9
2) Now let's look at the 2nd question. The number of red marbles to the number of blue marbles is the ratio we need to find.
- The number of red marbles is 7. This would be our first number or the numerator.
- The number of blue marbles is 9. This would be our second number or the denominator.
- Therefore, the ratio would be --> 7/9 or 7:9

Answer:
12 INCHES = 1FOOT
Step-by-step explanation:
Answer:
7p¹⁵/ 3q¹²
Step-by-step explanation:
From the question given above,
28p⁹q¯⁵ / 12p¯⁶q⁷
To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:
28p⁹q¯⁵ / 12p¯⁶q⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷
Recall:
Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ
Therefore,
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²
Recall:
X¯ⁿ = 1/Xⁿ
Therefore,
(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²
(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²
Hence,
28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²
Answer:
Step-by-step explanation:
Algebraic expression: 4x - 2y
Algebraic equation: 4x - 2y = 15
Term(s): 4x, -2y
Coefficient(s); 4, -2
Constant(s); no constants
Variable(s): x, y
expressions don't have an equal sign, equations do
terms are separated by operational signs (multiplication, division, addition, subtraction)
Coefficients are the numbers before variables
Constants aren't variables
Variables are letters
