Answer 2

thank you

Answer 3

3/16 + 4/6 + 2/5

equate it to a Number and clear fractions

Answer 4

find prime factors of each number and combine those terms that are the same in each and multiply

for example factors of 15 = 3 * 5
factors of 45 = 3^(2)*5
common factors are 3 and 5; so LCD = 3*5 = 15

Answer 5

3/16 + 4/6 + 2/5 = N

3(5)/16 + 4(5)/6 + 2(5)/5 = (5)N

15/16 + 10/3 + 2 = 5N

15(3)/16 + 10(3)/3 + 2(3) = 5(3)N

45/16 + 10 + 6 = 15N

45(16)/16 + 10(16) + 6(16) = 15(16)N

45 + 160 + 96 = 240N

lcd = 240
