Answer:11/14
Step-by-step explanation:
Let's multiply the numerators first. 22 x 1 is 22, so your numerator is 22.
The denominator: 7 x 4= 28, your denominator is 28.
Your answer <u><em>would</em></u> be 22/28.
However, we can simplify this.
22 and 28 are both divisible by 2.
22/2=11
28/2=14
Your final answer is <u><em>11/14</em></u>
