2/7. -. 7/2

Hope it helps

Answer 2

Answer:

63/2

Step-by-step explanation:

Multiplicative inverse of 4/9 is 9/4

and of 2/7 is 7/2

so 9/4 * 7/2

lcm of 2,4 is 4

7/2 becomes 14/4

how ??? I'll Make it easy easy for you lcm is 4 which should be the denominator so 2x2 is 4 now D is 4 and same with 7x2 is 14 so it becomes 14/4 and 9/4 will be the same because 4 id D already

now,

9/4 x 14/4 = now 4 is D for both so 9 x 14 is 126

so it is 126/4 now simplify 63/2
