Change 1 and 1/2 to an improper fraction.
(2*1+1)/2
= 3/2
---------then.....
7 * 3/2
= 21/2

To multiply a fraction with an integer, multiply the integer (in this case 14) with the numerator of the fraction (in this case 1), and then divide the result by the denominator (in this case 2). The answer is 7
To multiply the fractions ( \frac{1}{3} ) and ( \frac{1}{7} ), you multiply the numerators and the denominators. This gives ( \frac{1 \times 1}{3 \times 7} = \frac{1}{21} ). Therefore, ( \frac{1}{3} \times \frac{1}{7} = \frac{1}{21} ).
To divide four sevenths by one half, you can multiply four sevenths by the reciprocal of one half. The reciprocal of one half is two, so the calculation becomes ( \frac{4}{7} \times 2 = \frac{8}{7} ). Therefore, four sevenths divided by one half equals eight sevenths, which can also be expressed as 1 and 1/7.
Multiply by 7 means times a number by 7.
To get 294, you can multiply the numbers 2, 3, 7, and 7 together: (2 \times 3 \times 7 \times 7 = 294). Another combination could be 1, 2, 3, and 49, since (1 \times 2 \times 3 \times 49 = 294). Various combinations exist, but these two are valid examples.
7 times 8 is 56 then you multiply 56 times 1=56

(1/2) / (1+1/7) = (1/2) / (7/7 + 1/7) = (1/2) / (8/7). Note that 7/7 = 1. Take reciprocal of denominator then multiply.(1/2) / (8/7) = (1/2) * (7/8) = 7/16 [multiply the numerators and multiply the denominators]
To divide four sevenths by one half, you can multiply four sevenths by the reciprocal of one half. The reciprocal of one half is two, so the calculation becomes ( \frac{4}{7} \times 2 = \frac{8}{7} ). Therefore, four sevenths divided by one half equals eight sevenths, which can also be expressed as 1 and 1/7.

Multiplying any number by a half gets you the same number you would get if you were to divide the number by 2. When multiplying by 1/2, you are taking half the amount you started with. 14 x .5=7. You can multiply 14 by the 1 in 1/2, and create 14/2. Remember that 14 is the same thing as 14/1. You simplify 14/2 to 7/1, which is just 7.
Multiply by 7 means times a number by 7.
For purposes of calculation, 1/2 OF something is the same as 1/2 TIMES something. Therefore, you only need to multiply 1/2 times 1 and 3/4. Here are two ways to do this:1) Convert 1 and 3/4 to a mixed fraction. Then multiply the numerators, and the denominators. 2) Remember that 1 and 3/4 means 1 + 3/4. Use the distributive property, i.e., multiply 1/2 times 1, multiply 1/2 times 3/4, and add the results. The first method is simpler in this case, but it is convenient to know both methods, since sometimes the second method is easier.
7 1/2 = 15/2 When dividing by a fraction, invert and multiply 7 1/2 divided by 1/2 = 15/ 2 x 2/1 = 15
multiply by the reciprocal if you had 1/3 divided by 5/7 you would do 1/3 times 7/5
