Solve for n. {:[(12)/(5)=(n)/(8)],[n=]:}

Divide total by roll amount: To find the number of rolls, divide the total amount of tape needed by the amount of tape on each roll. 8,000 cm ÷ 2,000 cm/roll = 4 rollsCross multiply for n: Cross multiply to solve for n. (12)(8) = (5)(n)Calculate product: Calculate the product on each side. 96 = 5nDivide by 5 for n: Divide both sides by 5 to solve for n. 96 ÷ 5 = nPerform division: Perform the division. n = 19.2

Q. Solve for

n

\newline

\begin{array}{l} \frac{12}{5}=\frac{n}{8} \\ n= \end{array}

Divide total by roll amount: To find the number of rolls, divide the total amount of tape needed by the amount of tape on each roll. $8,000 \, \text{cm} \div 2,000 \, \text{cm}/\text{roll} = 4 \, \text{rolls}$
Cross multiply for $n$ : Cross multiply to solve for $n$ . $(12)(8) = (5)(n)$
Calculate product: Calculate the product on each side. $\newline$ $96 = 5n$
Divide by $5$ for $n$ : Divide both sides by $5$ to solve for $n$ . $96 \div 5 = n$
Perform division: Perform the division. $n = 19.2$
