9/8/7/6*14/3*20*22/11

1 answer

To solve the expression \( \frac{9}{8} \div 7 \div 6 \times \frac{14}{3} \times 20 \times \frac{22}{11} \), we will follow the order of operations (PEMDAS/BODMAS).

First, let's rewrite the expression in a more manageable form:

\[ \frac{9}{8} \div 7 \div 6 \times \frac{14}{3} \times 20 \times \frac{22}{11} \]

Now, let's process the divisions and multiplications step by step:

  1. Convert divisions to multiplications by taking the reciprocal:

\[ \frac{9}{8} \times \frac{1}{7} \times \frac{1}{6} \times \frac{14}{3} \times 20 \times \frac{22}{11} \]

  1. Perform multiplication of the fractions:

Now we can multiply the numerators together and the denominators together:

Numerator: \[ 9 \times 1 \times 1 \times 14 \times 20 \times 22 = 9 \times 14 \times 20 \times 22 \]

Denominator: \[ 8 \times 7 \times 6 \times 3 \times 1 \times 11 = 8 \times 7 \times 6 \times 3 \times 11 \]

Calculating the numerator:

  • \(9 \times 14 = 126\)
  • \(126 \times 20 = 2520\)
  • \(2520 \times 22 = 55440\)

Calculating the denominator:

  • \(8 \times 7 = 56\)
  • \(56 \times 6 = 336\)
  • \(336 \times 3 = 1008\)
  • \(1008 \times 11 = 11088\)

Now, we have:

\[ \frac{55440}{11088} \]

Next, we simplify this fraction. We can divide both the numerator and the denominator by 11088:

Calculating:

\[ 55440 \div 11088 = 5 \]

So, the expression simplifies to:

\[ \frac{55440}{11088} = 5 \]

Therefore, the final answer is:

\[ \boxed{5} \]
