2/3 = 4/6 because you can multiply the top and bottom numbers (numerator and denominator) by any number. However, you MUST multiply both the top and bottom number. In this case, you multiply 2/3 by 2. So, it would be 2 times 2 over 3 times 2. That gets you 4/6. 2/3=4/6, so they are congruent fractions.
You change 1 1/3 into a mixed number and then multiply. 2/5 times 4/3 Answer= 8/15
Multiply 2 x 2 x 3 x 3
Now, this is very simple. All you have to do is multiply 7 and 2 to get 14 and put it over 2
(4 / 5) x (2 / 3)? To multiply fractions, simply multiply straight across. So 4 x 2 = 8, and 5 x 3 = 15, so you get 8 over 15. Simple!
