Answer:
For the first one, the answer would be:
2/3 * 3/8 = 6/24 because, all you have to do is multiply straight across.
2 * 3 = 6 and 3 * 8 = 24
6/24 can be simplified to 1/4 because 6 with go into the denominator 4 times, so the simplified fraction will be 1/4.
(Im not so sure what to do about the second one, so I would need to see what the options look like)
For the third:
The answer would be 3/3, because:
2 * 3 = 6
5 * 3 = 15
And the result fraction is 6/15, which matches what the image shows!
