hi. im doing a PIZZAZ! sheet if your familar with it? anyway one of the questions reads,what is 7/12 - 1/3=? please HELP
7/12 - 1/3
7/12 - 4/12 = ?
ms.sue thx 4 trying
Did you figure out the answer?
Can you subtract 7 - 4?
oh, yes now i get it
Of course, I can help you with that! To solve the equation 7/12 - 1/3, we need to find a common denominator for the two fractions. The common denominator is the smallest multiple that both denominators, in this case, 12 and 3, share. In this case, the smallest multiple that works is 12.
To convert 7/12 to a fraction with a denominator of 12, we need to multiply the numerator and the denominator by the same number. In this case, we multiply 7 by 1. Since 12 is already our target denominator, we multiply the numerator and the denominator of 7/12 by 3:
(7 * 3) / (12 * 3) = 21/36
Now, let's convert 1/3 to a fraction with a denominator of 12. Similar to the previous step, we multiply the numerator and the denominator of 1/3 by 4, as 4 * 3 = 12:
(1 * 4) / (3 * 4) = 4/12
Now that both fractions have a common denominator of 12, we can subtract them:
(21/36) - (4/12)
To subtract fractions, we need to have the same denominator, which we already have. So we can proceed by subtracting the numerators while keeping the denominator the same:
(21 - 4) / 12 = 17/12
Therefore, 7/12 - 1/3 is equal to 17/12.
