To multiply (7 \frac{1}{2}) by (1 \frac{1}{2}), first convert the mixed numbers to improper fractions. (7 \frac{1}{2} = \frac{15}{2}) and (1 \frac{1}{2} = \frac{3}{2}). Now, multiply the fractions:
[ \frac{15}{2} \times \frac{3}{2} = \frac{45}{4}. ]
Finally, convert (\frac{45}{4}) back to a mixed number, which is (11 \frac{1}{4}).

What is 7 12 divided by 1 12?
That's the same as 7/12 x 12/1 = 84/12 = 7
Solve for x in x plus 1 over x equals -7 over x - 12?
You have : -------------- ( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 ) Multiply both sides by ( x ) ( x - 12 ) and get : ( x + 1 ) ( x - 12 ) = ( -7 ) ( x ) x^2 - 12x + x - 12 = -7x x^2 - 4x - 12 = 0 Factor the above : ( x - 6 ) ( x + 2 ) = 0 There are two roots : x = 6 <------------------ x = -2 <---------------
6-x plus 12 equals 10x plus 7 how much x equals?
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
What is four times three sevenths?
3 x 4/7 is similar to 3/1 x 4/7 The answer is 12/7 because you multiply the numerators together (3 x 4 = 12) and the denominators together (1 x 7 = 7).
