Answer:
Step-by-step explanation:
Four has 2 twos.
22 has 1 two and 1 eleven.
So the least common denominator is
2 * 2 * 11
44
1/4 has to have numerator and denominator multiplied by 11
1*11/4*11 = 11/44
7/22 needs just 1 two multiplied by the common 2 to make the denominator common
7*2 / 22*2 = 14 / 44
