Question

Each batch needs 1/4 but gina only has 9/10 left how many batches can Gina make

Answer 1

3 batches with a remainder of 2/5.

Explanation:

1/4 converted to a decimal is 0.25, while 9/10 converted to a decimal is 0.9

The closest we can get without surpassing 9/10's absolute value is 1/4 x 3, giving you 0.75, or 3/4 in this matter.

Subtracting will get you to 0.15, which the difference of 0.25 - 0.15 is equivalent to 0.1. Converting that back to a fraction is
`3(2)/(5)`, and 0.25 divided by 5 is 0.05.
