A stationery shop orders a batch of pens from a factory.
The factory could make the batch of pens in
20 days using 12 machines.
Due to a fault, only 8 machines were used for the
first 9 days.
All 12 machines were used from day 10 onwards.

Work out the total number of days taken to make
the batch of pens.

both equations and proportions are better.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

1. minimum

2. 6400

3. eight

hope this !
