A. 45/70
5/7 × 9/10
Multiply the numerator with the other numerator, and denominator with the other denominator.
5 × 9
7 × 10
It becomes 45/70.
B. 23/30
1 3/5 - 5/6
In adding/subtracting fractions, their denominators must be equal. Make them so by finding the LCM of both denominators.
5 and 6 would have an LCM of 30. Make it so the numerator and new denominator still have equal proportion as the first fraction you started with.
1 3/5 becomes 1 3(6) / 5(6), or 1 18/30
5/6 becomes 5(5) / 6(5), or 25/30
You can now subtract both fractions.
1 18/30 - 25/30
The minuend (if the presence of 1 whole is ignored) is smaller than the subtrahend. To fix this, borrow the 1 whole from 1 18/30. 1 in this fraction would be 30, so add 30 to the fraction and remove the 1 in the fraction.
48/30 - 25/30
Subtract.
=23/30.
