What is 3 tenths x 5/9 and 2 thirds x 3 fourths

3/10x 5/9 would be 15/90 because Well, when multiplying fractions it doesn't matter if the denominators are different. You simply just multiply the two denominators to get your answer and the same for the numerators. And the same for 2 thirds and 3/4 it would be 6/12

1st question: 1/2

2/3 x 3/4
To make it easier you can divide the numbers with common factors numbers leaving you with 2 x 1/4= 2/4= 1/2

2nd question: 1/6

Again you can divide numbers with common factors so first start with 3 and 9 as they have common factors of 3: 3/10 x 5/9= 1/10 x 5/3
Then start with 5 and 10 which has the common factor of 5: 1/2 x 1/3
Now multiply them giving you 1/6

The answer is the third choice
