What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
12 x b = 480
Dividing by 12 on both sides , we get
b = 40
Hence , the value of b = 40

Final answer:
To divide 7/9 by 2 13/18, convert the mixed number to an improper fraction, then multiply the fractions and simplify. The result is 42/141.
Explanation:
To divide 7/9 by 2 13/18, we need to convert the mixed number 2 13/18 into an improper fraction. To do this, we multiply the whole number (2) by the denominator of the fraction (18) and add the numerator (13). This gives us 47. So, 2 13/18 can be written as the improper fraction 47/18.
Now, we can divide 7/9 by 47/18. We multiply the first fraction by the reciprocal of the second fraction (flip the numerator and denominator). So, (7/9) ÷ (47/18) becomes (7/9) × (18/47).
To multiply fractions, we multiply the numerators together and the denominators together. This gives us (7/9) × (18/47) = (7 × 18) / (9 × 47) = 126/423.
Lastly, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor. The GCD of 126 and 423 is 3. Dividing both numerator and denominator by 3 gives us the simplified answer: 42/141.
