Question

What is a common denominator for 6, 7, and 5? I have to add 1/6 + 5/7 + 4/5.
Super easy, just not thinking properly...

Answer 1

the common denominator is 210 since you multiply all the denominators together 6x5x7=210. so then you should have 1(5x7)/210 + 5(6x7)/210 + 4(5x6)/210

Answer 2

this should give y ou 35/210 + 5(6x5)/210 my bad on the previous error which is 150/210 + 4(6x7)/210 again sorry which is 168/210

Answer 3

35+ 150+ 168= 353/210 should be your answer

Answer 4

ooh got it. thanks!
