Answer 1

Answer:

1) there are two fractions in this equation=2/5 & 4/9.

first do the reciprocal of them=5/2 & 9/4.

now multiply the results together=45/8.

verify

reciprocal of 2/5 x reciprocal of 45/8 = 4/9.

if the result is equal to 4/9 then the answer right

after doing reciprocals-.

5/2 x 8/45=4/9.

cut the no.'s which can be

we get -.

4/9=4/9.

therefore the answer is= 45/8.

2) 3 1/3 = 10/3

0.3 = 3/10

a * 1/a =1

then 1/a is multiplicative inverse of a

0.3* 3 1/3 = 3/10 * 10/3 =1

therefore 0.3 is multiplicative inverse of 3 1/3
