Stupid algebra again

1 year ago3/5 + 1/2

1 year agoYou can’t add fractions that have different denominators.

1 year agoDo you know what the denominator is?

1 year agoYes the bottom number

1 year agoI got it. •-•

1 year agoYou sure?

1 year agoYes don’t stalk my DMs…

1 year ago?

1 year agoI got help :D

1 year agoOkay

1 year ago3/5 + 1/2 You would find what is called the least common denominator. This is also the least common multiple. A multiple is a number multiplied by an integer (whole number). You need to find a multiple that both denominators share. Thus, least common denominator. 5 times 2 = 10 2 times 5 = 10 We must alter the form of these fractions, but retain their value. Do so by multiplying by 1. \[\frac{ 3 }{ 5 } \times \frac{ 2 }{ 2} = \frac{ 6 }{ 10 }\] \[\frac{ 1 }{ 2 } \times \frac{ 5 }{ 5 } = \frac{ 5 }{ 10 }\] Similar to in Algebra, 'what you do to one side, do to the other." What you do to the bottom, do to the top. This keeps the value the same, and also 5/5 = 1 and 2/2 = 1. Multiply by 1 means the number stays the same \[\frac{ 6 }{10 } + \frac{ 5 }{ 10 } = \frac{ 11 }{ 10 }\]
