i need help with these 2 math ? 3/4-3/8 and 1/2-2/3 thank u
3/4 -3/8
6/8-3/8
=3/8
1/2-2/3
3/6-4/6
=-1/6
-3/6 or 3/6?
Of course! I would be happy to help you with these math questions. Let's break them down step by step.
1) 3/4 - 3/8:
To subtract fractions, we need to have the same denominator. The least common multiple (LCM) of 4 and 8 is 8.
To convert 3/4 to have a denominator of 8, we multiply both the numerator and denominator by 2:
3/4 = (3 * 2) / (4 * 2) = 6/8
Now we can subtract:
6/8 - 3/8 = (6 - 3) / 8 = 3/8
So, 3/4 - 3/8 = 3/8.
2) 1/2 - 2/3:
Again, to subtract fractions, we need to have the same denominator. The LCM of 2 and 3 is 6.
To convert 1/2 to have a denominator of 6, we multiply both the numerator and denominator by 3:
1/2 = (1 * 3) / (2 * 3) = 3/6
To convert 2/3 to have a denominator of 6, we multiply both the numerator and denominator by 2:
2/3 = (2 * 2) / (3 * 2) = 4/6
Now we can subtract:
3/6 - 4/6 = (3 - 4) / 6 = -1/6
So, 1/2 - 2/3 = -1/6.
Therefore, the solutions are:
3/4 - 3/8 = 3/8
1/2 - 2/3 = -1/6
