-- Multiply the numerators to get the numerator of the product.
-- Multiply the denominators to get the denominator of the product.
-- Simplify the product if it's possible and you feel like it.
you switch i over 3 to 3 over 1 and then you multiply across
11 over 12 + 1 over 3= 11 over 12 + 4 over 12 = 15 over 12 or 1 and 3 over 12 or 1 and 1 over 4
Its 8 over 11. Because you add the 1 + 3 + 4 = 8 over 11.
3/4
1 x 33, 3 x 11
11/12-3/4= 11/12 and 3/4 have different denominators. So we multiply 4 by 3 to get the denominators the same. If we multiply 4 by 3, we should also multiply 3 by 3. 11/12-9/12=2/12 If it asks us it in the simplest form, 2/12 find the LCM, 2. And divide it by 2, 2/12=1/6.
Add 1/4 and 2/3. This results in 11/12. Then divide by 2 (or multiply by 1/2). The answer is 11/24 or about .458333.
11 / (3/8) In order to divide by a fraction, first put the number 11 over 1 to make it a fraction too. (11/1)/(3/8) and then flip 3/8 upside down, then multiply. (11/1)*(8/3) When you multiply fractions, just go straight across. Top times top, bottom times bottom. 88/3
11/6 + 1/3 = 11/2
11 over 3
-11
it is 3 over 32 (you have to cross multiply them)
2x - 3y = 4 x + 4y = 3 Write the augmented matrix: 2 -3 4 1 4 3 Multiply the first row by 1/2: 1 -3/2 2 1 4 3 Subtract the second row from the first row: 1 - 3/2 2 0 -11/2 -1 Multiply the second row by -2/11: 1 -3/2 2 0 1 2/11 Multiply the second row by 3/2 and add it to the first row: 1 0 25/11 0 1 2/11 Thus x = 25/11 and y = 2/11 Check:
9 over 11.
3 2/3 x 5/11 = 1 2/3
1000,000,000,000,000,000,00,000 * * * * * 1/3 * 6/12 = 1/3 * 1/2 = 1/6
It is: 11/12 -3/4 = 1/6
