Option A
is one way to determine the factors of
by grouping
<em><u>Solution:</u></em>
Factoring by grouping means that you will group terms with common factors before factoring
<em><u>Given expression is:</u></em>

Group the first two terms together and then the last two terms together.

We can see that
is common in first two terms
And 3 is common in last two terms
Factor them out


Thus option A is correct
For this case we can make the following rule of three:
2/9 ------> 3/5
x ---------> 1
Clearing x we have:
x = (1 / (3/5)) * (2/9)
Rewriting we have:
x = (5/3) * (2/9)
x = 10/27
Answer:
he irons 10/27 of his shirt every minute
