first make 10 2/7 an improper fraction. so now u have 72/7 x 7/9. remeber: numerator x numerator/denominator x denominator. 72 x 7=504. 7 x 9=63 504/63=8

Step 1)Take the mixed fraction and make it an improper fraction.Multiply the whole number by the denominator and add the result to the numerator.
10 x 7 =70 +2 =72/7
Step 2)Multiply arcoss
_72_ x _7_ = _504_
7 x 9 = 63
Step 3) Simplify the fraction into lowest terms
_504_ = 8
63
So your answer is 8

First: take the mixed fraction and make it an improper fraction > multiply the whole number by the denominator and add the result to the numerator. Keep the result over the original denominator.
10 * 7 = 70
70 + 2 = 72
> 72/7 * 7/9
Sec: multiply the numerators and the denominators...
(72*7)/(7*9)
504/63
Third: simplify the fraction into lowest terms, if possible...
= 8

10 2/7 x 7/9=72/7 x 7/9
n*n over d*d.
72x7=504.
7x9=63.
504/63=56/7=8/1.

may I have seen your questions you have to learn fractions they are not that hard give your brain a chance to learn, it is only a matter of multiply, divide add and subtract.
Your question's answer is:
10*2/7 *7/9
20/7*7/9
20*7/7*9
20/9

First turn mixed numbers into improper fractions.
This means turn 10 2/7 into (10*2)/7, or 20/7.
The equation turns into (20/7) * (7/9). multiply top by top, and bottom by bottom, to get 140/63.
