So numerator = denominator * fractional value (quotient) or denominator = numerator/fractional value (quotient) = numerator/denominator.
Solve the problem:
1、? / 10=6 ? = 10*6=60 ; 6=30/? ? = 1/5
4=? /2 ? =8 ; 4=? /4 ? = 16 ; 4=? / 10 ? =40
2. If the numerator of 8/32 is 1, then the numerator denominator can be divided by 8 to get 1/4.
The denominator of 3/5 should be 25. Multiply the denominator by 5 to get 15/25.
7/9 numerator should be 56 numerator denominator multiplied by 8 to get 56/72;
3, numerator denominator plus or minus a number can't guarantee the fractional value unchanged, so
7/8 numerator plus 14 is 2 1, which is three times that of 7. The numerator denominator can be multiplied by 3 to get a score of 24, which is positive (16).
Similarly, the denominator of 36/48 minus 34 is 14 equals 48 times 7/24, and the denominator of numerator equals 7/24 times 36 times 7/24 = 21/236-21/2 = 51/2 (here
