Answer 1

To solve the equation 21/22 divided by 7/18, we can follow these steps:

Step 1: Convert the division into multiplication by taking the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, 7/18 becomes 18/7.

Step 2: Multiply the two fractions together. Multiplying fractions is done by multiplying the numerators together and the denominators together. Therefore, (21/22) * (18/7) can be calculated as follows:

(21 * 18) / (22 * 7)

Step 3: Simplify the resulting fraction, if possible. In this case, we can simplify the numerator and denominator by finding their greatest common divisor (GCD) and dividing both by it. The GCD of 21 and 22 is 1, and the GCD of 18 and 7 is also 1. Therefore, the fraction cannot be simplified further.

So, the final result of the equation 21/22 divided by 7/18 is:

(21 * 18) / (22 * 7) = 378 / 154
