1/2 + 1/3 * 1/7 = 1/2 + 1/21 = 21/42 + 2/42 = 23/42
4/9 * 3/14 = 2/21
6/63=3(2)/3(21)=2/21 2/21 times.
2/3 x 21 = 14
(20/21)/(2/3) = (20/21) x (3/2) = 10/7 = 1 and 3/7 = 1.428571429
21/2
(3/4)(16/21)(7/10)=(2/5) or 2 over 5, or 2 fifths.
21
=10/21
- 10/ 21
3/7 x 7/2 = 21/14 = 3/2
The result is 6 2/3
2/3*6/7 = 12/21 = 4/7 in its lowest terms
1664/21 (52/3) * (32/7) (52*32)/(3*7)
4/7 * 2/3 = 8/21.4/7 * 2/3 = 8/21.4/7 * 2/3 = 8/21.4/7 * 2/3 = 8/21.
1/2 + 1/3 * 1/7 = 1/2 + 1/21 = 21/42 + 2/42 = 23/42
In order to do this problem, you need to multiply directly. So, 2 over 3 times 6 over 7. First, we're going to do the top. 2 times 6 is 12. The bottom is 3 times 7, which is 21. Your answer is 12 over 21, but they can be both reduced by 3, so your final answer is 4 over 7.
