Question #0089b

Answer 1

To Increase: `xx ("big")/("small")`

To Decrease: `xx ("small")/("big")`

Explanation:

Numbers less than `1` are proper fractions.

When you multiply by a proper fraction you are finding a fraction of something... a half of, a third of, three-fifths of ... etc.

The answer will ALWAYS be smaller..

`12 xx 2/3 = 12 xx2 div 3 = 8" "larr` times by `2` and divide by `3`

Numbers greater than `1` are improper fractions.

When you multiply by an improper fraction, the answer will ALWAYS be bigger. This is because you are multiplying by a bigger value and dividing by a smaller number.

`12 xx 5/4 = 12 xx 5 div 4 = 15" "larr` times by `5` and divide by `4`

To Increase: `xx ("big")/("small")`

To Decrease: `xx ("small")/("big")`
