Answer: 689 + 30/32
Step-by-step explanation:
A reduction of A by B, means that we need to solve:
A - B.
So if we want to reduce 738 and 7/32 by 48 and 9/32 we have to solve:
(738 + 7/32) - (48 + 9/32)
we can separate it into whole and fraction:
(738 - 48) + (7/32 - 9/32)
690 - 2/32
But we usually don't want a negative fraction, so we can use that:
1 = 32/32
690 - 2/32 = 689 + 1 - 2/32 = 689 +32/32 - 2/32 = 689 + 30/32
