Best ResponseYou've already chosen the best response.1dw:1354103213183:dwbasically the fish type thing represents what is being multiplied so for example lets say we have two fractions a/b + c/d dw:1354103176755:dw to add them the general method is to do (ad +bc)/bd

Best ResponseYou've already chosen the best response.0dw:1354106538781:dw\[\frac{ 5}{ 11 } + \frac{ 5 }{ 7 }\]Find a least common factor of 7 & 11 to find the LCD. Factors of 11: 11, 22, 33, 44, 55, 66, 77 Factors of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77 Least common factor is 77. 11 times 7 = 77 so multiply both the numerator and denominator by 7. \[\frac{ 5 }{ 11 } \times7 = \frac{35 }{77 }\] 7 times 11 = 77 so multiply both the numerator and denominator by 11. \[\frac{ 5 }{ 7 } \times 11 = \frac{ 55 }{ 77 }\] NOW you can add the fractions: \[\frac{ 35 }{ 77 } + \frac{ 55 }{ 77 } = \frac{ (35 + 55) }{ 77 } = \frac{ 20 }{ 77 }\] So: \[\frac{ 5}{ 11 } + \frac{ 5 }{ 7 }\ =\frac{ 20 }{ 77 }\]
